text: Other convicted co-conspirators were sentenced to prison, including Ethel's brother, David Greenglass (who had made a plea agreement), Harry Gold, and Morton Sobell. Klaus Fuchs, a German scientist working in Los Alamos, was convicted in the United Kingdom.


title: Julius and Ethel Rosenberg

text: For decades many people including the Rosenbergs' sons (Michael and Robert Meeropol) maintained that Julius and Ethel were innocent of spying on their country and were victims of Cold War paranoia.


title: Julius and Ethel Rosenberg

text: The extent of the Rosenbergs' activities came to light, however, when the U.S. government declassified information about them after the fall of the Soviet Union. This declassified information included a trove of decoded Soviet cables (code-name: Venona), which detailed Julius's role as a courier and recruiter for the Soviets, and information about Ethel's role as an accessory who helped recruit her brother David into the spy ring and did clerical tasks such as typing up documents that Julius then passed to the Soviets. In 2008, the National Archives of the United States published most of the grand jury testimony related to the prosecution of the Rosenbergs.


title: Julius and Ethel Rosenberg

text: Julius Rosenberg was born on May 12, 1918, in New York City to a family of Jewish immigrants from the Russian Empire. The family moved to the Lower East Side by the time Julius was 11. His parents worked in the shops of the Lower East Side as Julius attended Seward Park High School. Julius became a leader in the Young Communist League USA while at City College of New York during the Great Depression. In 1939, he graduated with a degree in electrical engineering.


title: Julius and Ethel Rosenberg

text: Ethel Greenglass was born on September 28, 1915, to a Jewish family in Manhattan, New York City. She had a brother, David Greenglass. She originally was an aspiring actress and singer, but eventually took a secretarial job at a shipping company. She became involved in labor disputes and joined the Young Communist League, where she met Julius in 1936. They married in 1939.


title: Julius and Ethel Rosenberg

text: Julius Rosenberg joined the Army Signal Corps Engineering Laboratories at Fort Monmouth, New Jersey, in 1940, where he worked as an engineer-inspector until 1945. He was discharged when the U.S. Army discovered his previous membership in the Communist Party. Important research on electronics, communications, radar and guided missile controls was undertaken at Fort Monmouth during World War II.


title: Julius and Ethel Rosenberg

text: According to a 2001 book by his former handler Alexander Feklisov, Rosenberg was originally recruited to spy for the interior ministry of the Soviet Union, NKVD, on Labor Day 1942 by former spymaster Semyon Semyonov. By this time, following the invasion by Nazi Germany in June 1941, the Soviet Union had become an ally of the Western powers, which included the United States after Pearl Harbor. Rosenberg had been introduced to Semyonov by Bernard Schuster, a high-ranking member of the Communist Party USA and NKVD liaison for Earl Browder. After Semyonov was recalled to Moscow in 1944 his duties were taken over by Feklisov.


title: Julius and Ethel Rosenberg

text: Rosenberg provided thousands of classified reports from Emerson Radio, including a complete proximity fuse. Under Feklisov's supervision, Rosenberg recruited sympathetic individuals into NKVD service, including Joel Barr, Alfred Sarant, William Perl, and Morton Sobell, also an engineer. Perl supplied Feklisov, under Rosenberg's direction, with thousands of documents from the National Advisory Committee for Aeronautics, including a complete set of design and production drawings for Lockheed's P-80 Shooting Star, the first U.S. operational jet fighter. Feklisov learned through Rosenberg that Ethel's brother David Greenglass was working on the top-secret Manhattan Project at the Los Alamos National Laboratory; he directed Julius to recruit Greenglass.


title: Julius and Ethel Rosenberg

text: In February 1944, Rosenberg succeeded in recruiting a second source of Manhattan Project information, engineer Russell McNutt, who worked on designs for the plants at Oak Ridge National Laboratory. For this success Rosenberg received a $100 bonus. McNutt's employment provided access to secrets about processes for manufacturing weapons-grade uranium.


title: Julius and Ethel Rosenberg

text: The USSR and the U.S. were allies during World War II, but the Americans did not share information with, or seek assistance from, the Soviet Union regarding the Manhattan Project. The West was shocked by the speed with which the Soviets were able to stage their first nuclear test, "Joe 1", on August 29, 1949. However, the head official of the Soviet nuclear project, Lavrentiy Beria, used foreign intelligence, which he did not trust by default, only as a third-party check, rather than giving it directly to the design teams, who he did not clear to know about the espionage efforts, and the development was indigenous; considering that the pace of the Soviet program was set primarily by the amount of uranium that it could procure, it is difficult for scholars to judge accurately how much time was saved, if any.


title: Julius and Ethel Rosenberg

text: In January 1950, the U.S. discovered that Klaus Fuchs, a German refugee theoretical physicist working for the British mission in the Manhattan Project, had given key documents to the Soviets throughout the war. Fuchs identified his courier as American Harry Gold, who was arrested on May 23, 1950.


title: Julius and Ethel Rosenberg

text: On June 15, 1950, David Greenglass was arrested by the FBI for espionage and soon confessed to having passed secret information on to the USSR through Gold. He also claimed that his sister Ethel's husband Julius Rosenberg had convinced David's wife Ruth to recruit him while visiting him in Albuquerque, New Mexico, in 1944. He said Julius had passed secrets and thus linked him to the Soviet contact agent Anatoli Yakovlev. This connection would be necessary as evidence if there was to be a conviction for espionage of the Rosenbergs.


title: Julius and Ethel Rosenberg

text: On July 17, 1950, Julius Rosenberg was arrested on suspicion of espionage based on David Greenglass's confession. On August 11, 1950, Ethel Rosenberg was arrested after testifying before a grand jury (see section, below).


title: Julius and Ethel Rosenberg

text: Another conspirator, Morton Sobell, fled with his family to Mexico City after Greenglass was arrested. They took assumed names and he tried to figure out a way to reach Europe without a passport. Abandoning that effort, he returned to Mexico City. He claimed that he was kidnapped by members of the Mexican secret police and driven to the U.S. border, where he was arrested by U.S. forces. The U.S. government claimed Sobell was arrested by the Mexican police for bank robbery on August 16, 1950, and extradited the next day to the United States in Laredo, Texas.


title: Julius and Ethel Rosenberg

text: Twenty senior government officials met secretly on February 8, 1950, to discuss the Rosenberg case. Gordon Dean, the chairman of the Atomic Energy Commission, said: "It looks as though Rosenberg is the kingpin of a very large ring, and if there is any way of breaking him by having the shadow of a death penalty over him, we want to do it." Myles Lane, a member of the prosecution team, said that the case against Ethel Rosenberg was "not too strong", but that it was "very important that she be convicted too, and given a stiff sentence." FBI director J Edgar Hoover wrote that "proceeding against the wife will serve as a lever" to make Julius talk.


title: Julius and Ethel Rosenberg

text: Their case against Ethel Rosenberg was resolved 10 days before the start of the trial, when David and Ruth Greenglass were interviewed a second time. They were persuaded to change their original stories. David originally had said that he had passed the atomic data he had collected to Julius on a New York street corner. After being interviewed this second time, he said that he had given this information to Julius in the living room of the Rosenbergs' New York apartment. Ethel, at Julius's request, had taken his notes and "typed them up." In her re-interview, Ruth Greenglass expanded on her husband's version:


title: Julius and Ethel Rosenberg

text: Julius then took the info into the bathroom and read it and when he came out he called Ethel and told her she had to type this information immediately ... Ethel then sat down at the typewriter which she placed on a bridge table in the living room and proceeded to type the information that David had given to Julius. As a result of this new testimony, all charges against Ruth Greenglass were dropped.


title: Julius and Ethel Rosenberg

text: On August 11, Ethel Rosenberg testified before a grand jury. For all questions, she asserted her right to not answer as provided by the U.S. Constitution's Fifth Amendment against self-incrimination. FBI agents took her into custody as she left the courthouse. Her attorney asked the U.S. commissioner to parole her in his custody over the weekend, so that she could make arrangements for her two young children. The request was denied. Julius and Ethel were put under pressure to incriminate others involved in the spy ring. Neither offered any further information. On August 17, the grand jury returned an indictment alleging 11 overt acts. Both Julius and Ethel Rosenberg were indicted, as were David Greenglass and Anatoli Yakovlev.


title: Julius and Ethel Rosenberg

text: The trial of the Rosenbergs and Sobell on federal espionage charges began on March 6, 1951, in the U.S. District Court for the Southern District of New York. Judge Irving Kaufman presided over the trial, with Assistant U.S. Attorney Irving Saypol leading the prosecution and criminal defense lawyer Emmanuel Bloch representing the Rosenbergs. The prosecution's primary witness, David Greenglass, said that he turned over to Julius Rosenberg a sketch of the cross-section of an implosion-type atom bomb. This was the "Fat Man" bomb dropped on Nagasaki, Japan, as opposed to a bomb with the "gun method" triggering device used in the "Little Boy" bomb dropped on Hiroshima.


title: Julius and Ethel Rosenberg

text: On March 29, 1951, the Rosenbergs were convicted of espionage. They were sentenced to death on April 5 under Section 2 of the Espionage Act of 1917, which provides that anyone convicted of transmitting or attempting to transmit to a foreign government "information relating to the national defense" may be imprisoned for life or put to death.


title: Julius and Ethel Rosenberg

text: Prosecutor Roy Cohn later claimed that his influence led to both Kaufman and Saypol being appointed to the Rosenberg case, and that Kaufman imposed the death penalty based on Cohn's personal recommendation. Cohn would go on later to work for Senator Joseph McCarthy, appointed as chief counsel to the investigations subcommittee during McCarthy's tenure as chairman of the Senate Government Operations Committee.


title: Julius and Ethel Rosenberg

text: In imposing the death penalty, Kaufman noted that he held the Rosenbergs responsible not only for espionage but also for American deaths in the Korean War:


title: Julius and Ethel Rosenberg

text: I believe your conduct in putting into the hands of the Russians the A-bomb years before our best scientists predicted Russia would perfect the bomb has already caused, in my opinion, the Communist aggression in Korea, with the resultant casualties exceeding 50,000 and who knows but that millions more of innocent people may pay the price of your treason. Indeed, by your betrayal you undoubtedly have altered the course of history to the disadvantage of our country.


title: Julius and Ethel Rosenberg

text: The US government offered to spare the lives of both Julius and Ethel if Julius provided the names of other spies and they admitted their guilt. The Rosenbergs made a public statement: "By asking us to repudiate the truth of our innocence, the government admits its own doubts concerning our guilt ... we will not be coerced, even under pain of death, to bear false witness".


title: Julius and Ethel Rosenberg

text: After the publication of an investigative series in the "National Guardian" and the formation of the National Committee to Secure Justice in the Rosenberg Case, some Americans came to believe both Rosenbergs were innocent or had received too harsh a sentence, particularly Ethel. A campaign was started to try to prevent the couple's execution. Between the trial and the executions, there were widespread protests and claims of antisemitism; the charges of antisemitism were widely believed abroad, but not among the vast majority in the United States. At a time when American fears about communism were high, the Rosenbergs did not receive support from mainstream Jewish organizations. The American Civil Liberties Union refused to acknowledge any violations of civil liberties in the case.


title: Julius and Ethel Rosenberg

text: Across the world, especially in Western European capitals, there were numerous protests with picketing and demonstrations in favor of the Rosenbergs, along with editorials in otherwise pro-American newspapers, and a plea for clemency from the Pope. President Eisenhower, supported by public opinion and the media at home, ignored the overseas demands.


title: Julius and Ethel Rosenberg

text: Jean-Paul Sartre, a Marxist existentialist philosopher and writer who won the Nobel Prize for Literature, described the trial as


title: Julius and Ethel Rosenberg

text: a legal lynching which smears with blood a whole nation. By killing the Rosenbergs, you have quite simply tried to halt the progress of science by human sacrifice. Magic, witch-hunts, autos-da-fé, sacrifices – we are here getting to the point: your country is sick with fear ... you are afraid of the shadow of your own bomb. Others, including non-Communists such as Jean Cocteau and Harold Urey, a Nobel Prize-winning physical chemist, as well as Communists or other left-leaning figures such as Nelson Algren, Bertolt Brecht, Albert Einstein, Dashiell Hammett, Frida Kahlo, and Diego Rivera, protested the position of the American government in what the French termed the U.S. Dreyfus affair. Einstein and Urey pleaded with President Truman to pardon the Rosenbergs. In May 1951, Pablo Picasso wrote for the communist French newspaper "L'Humanité", "The hours count. The minutes count. Do not let this crime against humanity take place." The all-black labor union International Longshoremen's Association Local 968 stopped working for a day in protest. Cinema artists such as Fritz Lang registered their protest. Pope Pius XII appealed to President Dwight D. Eisenhower to spare the couple, but Eisenhower refused on February 11, 1953. All other appeals were also unsuccessful.


title: Julius and Ethel Rosenberg

text: The execution was delayed from the originally scheduled date of June 18, because Supreme Court Associate Justice William O. Douglas had granted a stay of execution on the previous day. That stay resulted from intervention in the case by Fyke Farmer, a Tennessee lawyer whose efforts had previously been scorned by the Rosenbergs' attorney, Emanuel Hirsch Bloch.


title: Julius and Ethel Rosenberg

text: The execution was scheduled for 11 p.m. that evening, during the Sabbath, which begins and ends around sunset. Bloch asked for more time, filing a complaint that execution on the Sabbath offended the defendants' Jewish heritage. Rhoda Laks, another attorney on the Rosenbergs' defense team, also made this argument before Judge Kaufman. The defense's strategy backfired. Kaufman, who also stated his concerns about executing the Rosenbergs on the Sabbath, rescheduled the execution for 8 p.m.—before sunset and the Sabbath—the regular time for executions at Sing Sing.


title: Julius and Ethel Rosenberg

text: On June 19, 1953, Julius died after the first electric shock. Ethel's execution did not go smoothly. After she was given the normal course of three electric shocks, attendants removed the strapping and other equipment only to have doctors determine that Ethel's heart was still beating. Two more electric shocks were applied, and at the conclusion eyewitnesses reported that smoke rose from her head.


title: Julius and Ethel Rosenberg

text: The funeral services were held in Brooklyn on June 21. Ethel and Julius Rosenberg were buried at Wellwood Cemetery, a Jewish cemetery in Pinelawn, New York. "The Times" reported that 500 people attended, while some 10,000 stood outside:


title: Julius and Ethel Rosenberg

text: Senator Daniel Patrick Moynihan, vice-chairman of the Senate Select Committee on Intelligence, investigated how much the Soviet spy ring helped the USSR to build their bomb. Moynihan found that in 1945, physicist Hans Bethe estimated that the Soviets would be able to build their own bomb in five years. "Thanks to information provided by their agents", Moynihan wrote in his book "Secrecy", "they did it in four".


title: Julius and Ethel Rosenberg

text: Nikita Khrushchev, leader of the Soviet Union from 1953 to 1964, said in his posthumously-published memoir that he "cannot specifically say what kind of help the Rosenbergs provided us" but that he learned from Joseph Stalin and Vyacheslav Molotov that they "had provided very significant help in accelerating the production of our atomic bomb."


title: Julius and Ethel Rosenberg

text: Boris V. Brokhovich, the engineer who later became director of Chelyabinsk-40, the plutonium production reactor and extraction facility that the Soviet Union used to create its first bomb material, alleged that Khrushchev was a "silly fool". He said the Soviets had developed their own bomb by trial and error. "You sat the Rosenbergs in the electric chair for nothing", he said. "We got nothing from the Rosenbergs."


title: Julius and Ethel Rosenberg

text: The notes allegedly typed by Ethel apparently contained little that was directly used in the Soviet atomic bomb project. According to Alexander Feklisov, the former Soviet agent who was Julius's contact, the Rosenbergs did not provide the Soviet Union with any useful material about the atomic bomb: "He [Julius] didn't understand anything about the atomic bomb and he couldn't help us."


title: Julius and Ethel Rosenberg

text: The Venona project was a United States counterintelligence program to decrypt messages transmitted by the intelligence agencies of the Soviet Union. Initiated when the Soviet Union was an ally of the U.S., the program continued during the Cold War when it was considered an enemy.


title: Julius and Ethel Rosenberg

text: In 1995, the U.S. government made public many documents decoded by the Venona project, showing Julius Rosenberg's role as part of a productive ring of spies. For example, a 1944 cable (which gives the name of Ruth Greenglass in clear text) says that Ruth's husband David is being recruited as a spy by his sister (that is, Ethel Rosenberg) and her husband. The cable also makes clear that the sister's husband is involved enough in espionage to have his own codename ("Antenna" and later "Liberal"). Ethel did not have a codename, however, KGB messages which were contained in the Venona project's Vassiliev files, and which were not made public until 2009, revealed that both Ethel and Julius had regular contact with at least two KGB agents and were active in recruiting not only Ethel's brother David Greenglass, but also another Manhattan Project spy named Russell McNutt.


title: Julius and Ethel Rosenberg

text: The messages decoded by the Venona project were not made public during the Rosenbergs' trial, which relied instead on testimony from their collaborators. Nevertheless, these decryptions formed the background of U.S. government investigation and prosecutions of American communists during the Cold War period.


title: Julius and Ethel Rosenberg

text: In 2001, David Greenglass recanted his testimony about his sister having typed the notes. He said, "I frankly think my wife did the typing, but I don't remember." He said he gave false testimony to protect himself and his wife, Ruth, and that he was encouraged by the prosecution to do so. "My wife is more important to me than my sister. Or my mother or my father, OK? And she was the mother of my children."


title: Julius and Ethel Rosenberg

text: He refused to express remorse for his decision to betray his sister, saying only that he did not realize that the prosecution would push for the death penalty. He stated, "I would not sacrifice my wife and my children for my sister."


title: Julius and Ethel Rosenberg

text: At the grand jury, Ruth Greenglass was asked, "Didn't you write [the information] down on a piece of paper?" She replied, "Yes, I wrote [the information] down on a piece of paper and [Julius Rosenberg] took it with him." But at the trial, she testified that Ethel Rosenberg typed up notes about the atomic bomb.


title: Julius and Ethel Rosenberg

text: Numerous articles were published in 2008 related to the Rosenberg case. Deputy Attorney General of the United States William P. Rogers, who had been part of the prosecution of the Rosenbergs, discussed their strategy at the time in relation to seeking the death sentence for Ethel. He said they had urged the death sentence for Ethel in an effort to extract a full confession from Julius. He reportedly said, "She called our bluff", as she made no effort to push her husband to any action.


title: Julius and Ethel Rosenberg

text: In 2008, Morton Sobell was interviewed after the revelations from grand jury testimony. He admitted that he had given documents to the Soviet contact, but said these had to do with defensive radar and weaponry. He confirmed that Julius Rosenberg was "in a conspiracy that delivered to the Soviets classified military and industrial information ... [on] the atomic bomb," and "He never told me about anything else that he was engaged in."


title: Julius and Ethel Rosenberg

text: He said that he thought the hand-drawn diagrams and other atomic-bomb details that were acquired by David Greenglass and passed to Julius were of "little value" to the Soviet Union, and were used only to corroborate what they had already learned from the other atomic spies. He also said that he believed Ethel Rosenberg was aware of her husband's deeds, but took no part in them.


title: Julius and Ethel Rosenberg

text: In a subsequent letter to "The New York Times", Sobell denied that he knew anything about Julius Rosenberg's alleged atomic espionage activities, and that the only thing he knew for sure was what he himself did in association with Julius Rosenberg.


title: Julius and Ethel Rosenberg

text: In 2009, extensive notes collected from KGB archives were made public in a book published by Yale University Press: "Spies: The Rise and Fall of the KGB in America", written by John Earl Haynes, Harvey Klehr, and Alexander Vassiliev; Vassiliev's notebooks included KGB comments concerning Julius and Ethel Rosenberg.


title: Julius and Ethel Rosenberg

text: The notebooks make clear that the KGB considered Julius Rosenberg an effective agent and his wife Ethel an enthusiastic supporter of his work. According to Vassiliev, Julius and Ethel worked personally with KGB agents who were given the codenames "Twain" and "Callistratus" and were also described as being the ones who recruited Greenglass and McNutt for the Manhattan Project spy mission. Though the public release of Vassiliev's notebooks did not occur until 2009, the notebooks had in fact been originally intercepted during the Venona decryptions.


title: Julius and Ethel Rosenberg

text: The Rosenbergs' two sons, Michael and Robert, spent years trying to prove the innocence of their parents. They were orphaned by the executions and were not adopted by their many aunts or uncles, although they initially spent time under the care of their grandmothers and in a children's home. They were adopted by the social activist Abel Meeropol and his wife Anne, and assumed the Meeropol surname.


title: Julius and Ethel Rosenberg

text: After Morton Sobell's 2008 confession, they acknowledged their father had been involved in espionage, but said that whatever atomic bomb information he passed to the Russians was, at best, superfluous, that the case was riddled with prosecutorial and judicial misconduct, that their mother was convicted on flimsy evidence to place leverage on her husband, and that neither deserved the death penalty.


title: Julius and Ethel Rosenberg

text: Michael and Robert co-wrote a book about their and their parents' lives, "We Are Your Sons: The Legacy of Ethel and Julius Rosenberg" (1975). Robert wrote a later memoir, "An Execution in the Family: One Son's Journey" (2003). In 1990, he founded the Rosenberg Fund for Children, a nonprofit foundation that provides support for children of targeted liberal activists, and youth who are targeted as activists.


title: Julius and Ethel Rosenberg

text: Michael's daughter, Ivy Meeropol, directed a 2004 documentary about her grandparents, "Heir to an Execution", which was featured at the Sundance Film Festival.


title: Julius and Ethel Rosenberg

text: Their sons' current position is that Julius was legally guilty of the conspiracy charge, though not of atomic spying, while Ethel was only generally aware of his activities. The children say that their father did not deserve the death penalty and that their mother was wrongly convicted. They continue to campaign for Ethel to be posthumously legally exonerated.


title: Julius and Ethel Rosenberg

text: In 2015, following the most recent grand jury transcript release, Michael and Robert Meeropol called on U.S. President Barack Obama's administration to acknowledge that Ethel Rosenberg's conviction and execution was wrongful and to issue a proclamation exonerating her.


title: Julius and Ethel Rosenberg

text: In March 2016, Michael and Robert (via the Rosenberg Fund for Children) launched a petition campaign calling on President Obama and U.S. Attorney General Loretta Lynch to formally exonerate Ethel Rosenberg. In October 2016, both Michael and Robert Meeropol spoke with Anderson Cooper in an interview which aired on "60 Minutes". In January 2017 Senator Elizabeth Warren sent Obama a letter requesting consideration of the exoneration request.


title: Julius and Ethel Rosenberg

text: In 2021 Ethel's sons restarted the campaign to pardon Ethel, as they were more optimistic that President Biden will consider this favorably. "Ethel Rosenberg: A Cold War Tragedy" by Anne Sebba was published by Orion Books on 24 June 2021.


title: Mont Blanc

text: Mont Blanc ( ; , both meaning "white mountain") is the highest mountain in the Alps and Western Europe, rising above sea level. It is the second-most prominent mountain in Europe, after Mount Elbrus, and it is the eleventh most prominent mountain summit in the world.


title: Mont Blanc

text: It gives its name to the Mont Blanc massif which straddles parts of France, Italy and Switzerland. Mont Blanc's summit lies on the watershed line between the valleys of Ferret and Veny in Italy, and the valleys of Montjoie, and Arve in France. Ownership of the summit area has long been a subject of dispute between France and Italy.


title: Mont Blanc

text: The Mont Blanc massif is popular for outdoor activities like hiking, climbing, trail running and winter sports like skiing, and snowboarding. The most popular climbing route to the summit of Mont Blanc is the Goûter Route, which typically takes two days.


title: Mont Blanc

text: The three towns and their communes which surround Mont Blanc are Courmayeur in Aosta Valley, Italy; and Saint-Gervais-les-Bains and Chamonix in Haute-Savoie, France. The latter town was the site of the first Winter Olympics. A cable car ascends and crosses the mountain range from Courmayeur to Chamonix, through the Col du Géant. The Mont Blanc Tunnel, constructed between 1957 and 1965, runs beneath the mountain and is a major transalpine transport route.


title: Mont Blanc

text: Mont Blanc and adjacent mountains in the massif are predominately formed from a large intrusion of granite (termed a batholith) which was forced up through a basement layer of gneiss and mica schists during the Variscan mountain-forming event of the late Palaeozoic period. The summit of Mont Blanc is located at the point of contact of these two rock types. To the south west, the granite contact is of a more intrusive nature, whereas to the north east it changes to being more tectonic. The granites are mostly very-coarse grained, ranging in type from microgranites to porphyroid granites. The massif is tilted in a north-westerly direction and was cut by near-vertical recurrent faults lying in a north–south direction during the Variscan orogeny. Further faulting with shear zones subsequently occurred during the later Alpine orogeny. Repeated tectonic phases have caused breakup of the rock in multiple directions and in overlapping planes. Finally, past and current glaciation caused significant sculpting of the landscape into its present-day form.


title: Mont Blanc

text: The first systematic account of the minerals of the Mont Blanc area was published in 1873 by Venance Payot. His list, entitled "Statistique minéralogique des environs du Mt-Blanc", catalogued 90 mineral types although it also included those present only as very small components of rocks. If these are excluded, it is known today that at least 68 separate mineral species occur across the wider range of the Mont Blanc massif.


title: Mont Blanc

text: Located on the watershed between the Rhône and the Po, the massif of Mont Blanc is also situated between the two different climatic regions of the northern and western Alps, and that of the southern Alps. Climatic conditions on the Mer de Glace are similar to those found on the northern side of the Swiss Alps.


title: Mont Blanc

text: The climate is cold and temperate (Köppen climate classification "Cfb"), and is greatly influenced by altitude.


title: Mont Blanc

text: Being the highest part of the Alps, Mont Blanc and surrounding mountains can create their own weather patterns. Temperatures drop as the mountains gain in height, and the summit of Mont Blanc is a permanent ice cap, with temperatures around . The summit is also prone to strong winds and sudden weather changes. Because of its great overall height, a considerable proportion is permanently glaciated or snow-covered and is exposed to extremely cold conditions.


title: Mont Blanc

text: There is, however, significant variation in precipitation with altitude. For example, the village of Chamonix below Mont Blanc is at an elevation of approximately and receives around of annual precipitation, whilst the Col du Midi, which is at above sea level, receives significantly more, totalling . However, at an even higher altitude (near to the summit of Mont Blanc) precipitation is considerably less, with only around recorded, despite the latter measurements being taken at a height of .


title: Mont Blanc

text: Since 1760 Swiss naturalist Horace-Bénédict de Saussure began to go to Chamonix to observe Mont Blanc. He tried with the Courmayeur mountain guide Jean-Laurent Jordaney, a native of Pré-Saint-Didier, who accompanied De Saussure since 1774 on the Miage Glacier and on Mont Crammont.


title: Mont Blanc

text: The first recorded ascent of Mont Blanc (at the time neither within Italy nor France) was on 8 August 1786 by Jacques Balmat and the doctor Michel Paccard. This climb, initiated by Horace-Bénédict de Saussure, who gave a reward for the successful ascent, traditionally marks the start of modern mountaineering. The first woman to reach the summit was Marie Paradis in 1808.


title: Mont Blanc

text: At the scale of the Mont Blanc massif, the border between Italy and France passes along most of the main Alpine watershed, from the Aiguille des Glaciers to Mont Dolent, where it reaches the border with Switzerland. However, its precise location near the summits of Mont Blanc and nearby Dôme du Goûter has been disputed since the 18th century. Italian officials claim the border follows the watershed, splitting both summits between Italy and France, while French officials claim the border avoids the two summits, placing both of them entirely with France. The size of these two (distinct) disputed areas is approximately 65 ha on Mont Blanc and 10 ha on Dôme du Goûter.


title: Mont Blanc

text: Since the French Revolution, the issue of the ownership of the summit has been debated. From 1416 to 1792, the entire mountain was within the Duchy of Savoy. In 1723, the Duke of Savoy, Victor Amadeus II, acquired the Kingdom of Sardinia. The resulting state of Sardinia was to become preeminent in the Italian unification. In September 1792, the French Revolutionary Army of the Alps under Anne-Pierre de Montesquiou-Fézensac seized Savoy without much resistance and created a department of the Mont Blanc. In a treaty of 15 May 1796, Victor Amadeus III of Sardinia was forced to cede Savoy and Nice to France. In article 4 of this treaty, it says: "The border between the Sardinian kingdom and the departments of the French Republic will be established on a line determined by the most advanced points on the Piedmont side, of the summits, peaks of mountains and other locations subsequently mentioned, as well as the intermediary peaks, knowing: starting from the point where the borders of Faucigny, the Duchy of Aoust and the Valais, to the extremity of the glaciers or Monts-Maudits: first the peaks or plateaus of the Alps, to the rising edge of the Col-Mayor". This act further states that the border should be visible from the town of Chamonix and Courmayeur. However, neither is the peak of the Mont Blanc visible from Courmayeur nor is the peak of the Mont Blanc de Courmayeur visible from Chamonix because part of the mountains lower down obscure them.


title: Mont Blanc

text: After the Napoleonic Wars, the Congress of Vienna restored the King of Sardinia in Savoy, Nice, and Piedmont, his traditional territories, overruling the 1796 Treaty of Paris. Forty-five years later, after the Second Italian War of Independence, it was replaced by a new legal act. This act was signed in Turin on 24 March 1860 by Napoleon III and Victor Emmanuel II of Savoy, and deals with the annexation of Savoy (following the French neutrality for the plebiscites held in Tuscany, Modena, Parma and Romagna to join the Kingdom of Sardinia, against the Pope's will). A demarcation agreement, signed on 7 March 1861, defined the new border. With the formation of Italy, for the first time Mont Blanc was located on the border of France and Italy, along the old border on the watershed between the department of Savoy and that of Piedmont formerly belonging to the Kingdom of Savoy.


title: Mont Blanc

text: The 1860 act and attached maps are still legally valid for both the French and Italian governments. In the second half of the nineteenth century, on surveys carried out by a cartographer of the French army, Captain JJ Mieulet, a topographic map was published in France, which incorporated the summit into French territory, making the state border deviate from the watershed line, and giving rise to the differences with the maps published in Italy in the same period.


title: Mont Blanc

text: Modern Swiss mapping, published by the Federal Office of Topography, plots a region of disputed territory (statut de territoire contesté) around the summits of both Mont Blanc and the Dôme du Goûter. One of its interpretations of the French-Italian border places both summits straddling a line running directly along the geographic ridgeline (watershed) between France and Italy, thus sharing their summits equally between both states. However, a second interpretation places both summits, as well as that of Mont Blanc de Courmayeur (although much less clearly in the latter case), solely within France.

title: Mont Blanc

text: The first professional scientific investigations on the summit were conducted by the botanist–meteorologist Joseph Vallot at the end of the 19th century. He wanted to stay near the top of the summit to undertake detailed research, so he built his permanent cabin.


title: Mont Blanc

text: In 1890, Pierre Janssen, an astronomer and the director of the Meudon astrophysical observatory, considered the construction of an observatory at the summit of Mont Blanc. Gustave Eiffel agreed to take on the project, provided he could build on a rock foundation, if found at a depth of less than below the ice. In 1891, the Swiss surveyor Imfeld dug two horizontal tunnels below the ice summit but found nothing solid. Consequently, the Eiffel project was abandoned.


title: Mont Blanc

text: Despite this, the observatory was built in 1893. During the cold wave of January 1893, a temperature of was recorded on Mont Blanc, being the lowest ever recorded there.


title: Mont Blanc

text: Levers attached to the ice supported the observatory. This worked to some extent until 1906 when the building started leaning heavily. The movement of the levers corrected the lean slightly, but three years later (two years after Janssen's death), a crevasse started opening under the observatory. It was abandoned. Eventually the building fell, and only the tower could be saved "in extremis".


title: Mont Blanc

text: The mountain was the scene of two fatal air crashes; Air India Flight 245 in 1950 and Air India Flight 101 in 1966. Both planes were approaching Geneva Airport and the pilots miscalculated their descent; 48 and 117 people, respectively, died. The latter passengers included nuclear scientist Homi J. Bhabha, known as the "father" of India's nuclear programme.


title: Mont Blanc

text: In 1946, a drilling project was initiated to carve a tunnel through the mountain. The Mont Blanc tunnel would connect Chamonix, France, and Courmayeur, Italy, and become one of the major transalpine transport routes between the two countries. In 1965, the tunnel opened to vehicle traffic with a length of .


title: Mont Blanc

text: In 1999, a transport truck caught fire in the tunnel beneath the mountain. In total 39 people were killed when the fire raged out of control. The tunnel was renovated in the aftermath to increase driver safety. Renovations include computerised detection equipment, extra security bays, a parallel escape shaft, and a fire station in the middle of the tunnel. The escape shafts also have clean air flowing through them via vents. Any people in the security bays now have live video contact to communicate with the control centre. A remote site for cargo safety inspection was created on each side: Aosta in Italy and Passy-Le Fayet in France. Here all trucks are inspected before entering the tunnel. These remote sites are also used as staging areas to control commercial traffic during peak hours. The renovated tunnel reopened three years after the disaster.


title: Mont Blanc

text: The summit of Mont Blanc is a thick, perennial ice-and-snow dome whose thickness varies. No exact and permanent summit elevation can therefore be determined, though accurate measurements have been made on specific dates.


title: Mont Blanc

text: For a long time, its official elevation was . In 2002, the IGN and expert surveyors, with the aid of GPS technology, measured it to be .


title: Mont Blanc

text: After the 2003 heatwave in Europe, a team of scientists remeasured the height on 6 and 7 September. The team was made up of the glaciologist Luc Moreau, two surveyors from the GPS Company, three people from the IGN, seven expert surveyors, four mountain guides from Chamonix and Saint-Gervais and four students from various institutes in France. This team noted that the elevation was , and the peak was away from where it had been in 2002.


title: Mont Blanc

text: After these results were published, more than 500 points were measured to assess the effects of climate change and the fluctuations in the height of the mountain at different points. Since then, the elevation of the mountain has been measured every two years.


title: Mont Blanc

text: The summit was measured again in 2005, and the results were published on 16 December 2005. The height was found to be , more than the previous recorded height. The rock summit was found to be at , some west of the ice-covered summit.


title: Mont Blanc

text: From the summit of Mont Blanc on a clear day, the Jura, the Vosges, the Black Forest and the Massif Central mountain ranges can be seen, as well as the principal summits of the Alps.


title: Mont Blanc

text: Nowadays the summit is ascended by an average of 20,000 mountaineer tourists each year. It could be considered a technically easy, yet arduous ascent for someone well-trained and acclimatised to the altitude. From l'Aiguille du Midi (where the cable car stops), Mont Blanc seems quite close, being higher. But while the peak seems deceptively close, the La Voie des 3 Monts route (known to be more technical and challenging than other more commonly used routes) requires more ascent over two other mountains, Mont Blanc du Tacul and Mont Maudit, before the final section of the climb is reached and the last push to the summit is undertaken.


title: Mont Blanc

text: Each year climbing deaths occur on Mont Blanc, and on the busiest weekends, normally around August, the local rescue service performs an average of 12 missions, mostly directed to aid people in trouble on one of the normal routes of the mountain. Some routes require knowledge of high-altitude mountaineering, a guide (or at least an experienced mountaineer), and all require proper equipment. All routes are long and arduous, involving delicate passages and the hazard of rockfall or avalanche. Climbers may also suffer altitude sickness, occasionally life-threatening, particularly if they are not properly acclimatised.


title: Mont Blanc

text: A 1994 estimate suggests there had been 6,000 to 8,000 alpinist fatalities in total, more than on any other mountain. These numbers exclude the fatalities of Air India Flight 245 and Air India Flight 101, two planes that crashed into Mont Blanc. Despite unsubstantiated claims recurring in media that "some estimates put the fatality rate at an average of 100 hikers a year", actual reported annual numbers at least since the 1990s are between 10 and 20: in 2017, fourteen people died out of 20,000 summit attempts and two remained missing; with 15 in 2018 as of August.


title: Mont Blanc

text: A French study on the especially risky "Goûter couloir, on the normal route on Mont Blanc" and necessary rescue operations found that, between 1990 and 2011, there were 74 deaths "between the Tête Rousse refuge (3,187 m) and the Goûter refuge (3,830 m)". There were 17 more in 2012–15, none in 2016, and 11 in 2017.


title: Mont Blanc

text: Recent temperature rises and heatwaves, such as those of the summers of 2015 and 2018, have had significant impacts on many climbing routes across the Alps, including those on Mont Blanc. For example, in 2015, the Grand Mulets route, previously popular in the 20th century, was blocked by virtually impenetrable crevasse fields, and the Gouter Hut was closed by municipal decree for some days because of a very high rockfall danger, with some stranded climbers evacuated by helicopter.


title: Mont Blanc

text: In 2016 a crevasse opened at high altitude, also indicating previously unobserved glacial movements. The new crevasse forms an obstacle to be scaled by climbing parties on the final part of the itinerary to the top shared by the popular Goûter Route and the Grand Mulets Route.


title: Mont Blanc

text: In July 2014, an American entrepreneur and traveller Patrick Sweeney attempted to break the record with his nine-year-old son and 11-year-old daughter. They were caught in an avalanche, escaped death and decided not to pursue their attempt.


title: Mont Blanc

text: In August 2014, an unknown Austrian climber with his 5-year-old son were intercepted by mountain gendarmes at and forced to turn back.


title: Mont Blanc

text: On 5 August 2017, 9-year-old Hungarian twins and their mother were rescued from by helicopter while their father and family friend continued their summit attempt.


title: Mont Blanc

text: The Mont Blanc massif is being put forward as a potential World Heritage Site because of its uniqueness and its cultural importance, considered the birthplace and symbol of modern mountaineering. It would require the three governments of Italy, France and Switzerland to request UNESCO for it to be listed.


title: Mont Blanc

text: Mont Blanc is one of the most visited tourist destinations in the world, and for this reason, some view it as threatened. Pro-Mont Blanc (an international collective of associations for the protection of Mont Blanc) published in 2002 the book "Le versant noir du mont Blanc" (The black hillside of Mont Blanc), which exposes current and future problems in conserving the site.


title: Mont Blanc

text: In 2007, Europe's two highest toilets (at a height of 4,260 metres, 13,976 feet) were taken by helicopter to the top of Mont Blanc. They are also serviced by helicopter. They will serve 30,000 skiers and hikers annually, helping to alleviate the discharge of urine and faeces that spreads down the mountain face with the spring thaw, and turns it into 'Mont Marron'.


title: Mont Blanc

text: Global warming has begun to melt glaciers and cause avalanches on Mont Blanc, creating more dangerous climbing conditions.


title: 10 Downing Street

text: 10 Downing Street in London, also known colloquially in the United Kingdom as Number 10, is the official residence and executive office of the first lord of the treasury, usually, by convention, the prime minister of the United Kingdom. Along with the adjoining Cabinet Office at 70 Whitehall, it is the headquarters of the Government of the United Kingdom.


title: 10 Downing Street

text: Situated in Downing Street in the City of Westminster, London, Number 10 is over 300 years old and contains approximately 100 rooms. A private residence for the prime minister's use occupies the third floor and there is a kitchen in the basement. The other floors contain offices and conference, reception, sitting and dining rooms where the prime minister works, and where government ministers, national leaders and foreign dignitaries are met and hosted. At the rear is an interior courtyard and a terrace overlooking a garden. Adjacent to St James's Park, Number 10 is approximately from Buckingham Palace, the London residence of the British Monarch, and near the Palace of Westminster, the meeting place of both Houses of Parliament.


title: 10 Downing Street

text: Originally three houses, Number 10 was offered to Robert Walpole by King George II in 1732. Walpole accepted on the condition that the gift was to the office of First Lord of the Treasury. The post of First Lord of the Treasury has, for much of the 18th and 19th centuries and invariably since 1905, been held by the prime minister. Walpole commissioned William Kent to join the three houses and it is this larger house that is known as Number 10 Downing Street.


title: 10 Downing Street

text: Despite its size and convenient location near to Parliament, few early prime ministers lived at 10 Downing Street. Costly to maintain, neglected, and run-down, Number 10 was scheduled to be demolished several times, but the property survived and became linked with many statesmen and events in British history. In 1985, Margaret Thatcher said Number 10 had become "one of the most precious jewels in the national heritage".


title: 10 Downing Street

text: 10 Downing Street is Government property. Its registered legal title is held in the name of the secretary of state for levelling up, housing and communities (the secretary of state is a corporation sole).


title: 10 Downing Street

text: Number 10 Downing Street was originally three properties: a mansion overlooking St James's Park called "the House at the Back", a town house behind it and a cottage. The town house, from which the modern building gets its name, was one of several built by George Downing between 1682 and 1684.


title: 10 Downing Street

text: Downing, a notorious spy for Oliver Cromwell and later Charles II, invested in property and acquired considerable wealth. In 1654, he purchased the lease on land south of St James's Park, adjacent to the House at the Back within walking distance of parliament. Downing planned to build a row of terraced town houses "for persons of good quality to inhabit in ..." The street on which he built them now bears his name, and the largest became part of Number 10 Downing Street.


title: 10 Downing Street

text: Straightforward as the investment seemed, it proved otherwise. The Hampden family had a lease on the land that they refused to relinquish. Downing fought their claim, but failed and had to wait 30 years before he could build. When the Hampden lease expired, Downing received permission to build on land further west to take advantage of more recent property developments. The new warrant issued in 1682 reads: "Sir George Downing ... [is authorised] to build new and more houses ... subject to the proviso that it be not built any nearer than 14 feet of the wall of the said Park at the West end thereof". Between 1682 and 1684, Downing built a cul-de-sac of two-storey town houses with coach-houses, stables and views of St James's Park. Over the years, the addresses changed several times. In 1787 Number 5 became "Number 10".


title: 10 Downing Street

text: Downing employed Christopher Wren to design the houses. Although large, they were put up quickly and cheaply on soft soil with shallow foundations. Winston Churchill wrote that Number 10 was "shaky and lightly built by the profiteering contractor whose name they bear".


title: 10 Downing Street

text: The upper end of the Downing Street cul-de-sac closed off the access to St James's Park, making the street quiet and private. An advertisement in 1720 described it as "a pretty open Place, especially at the upper end, where are four or five very large and well-built Houses, fit for Persons of Honour and Quality; each House having a pleasant Prospect into St James's Park, with a Tarras Walk". The cul-de-sac had several distinguished residents: George Granville, 1st Baron Lansdowne from 1692 to 1696 and the Earl of Grantham from 1699 to 1703.


title: 10 Downing Street

text: Downing did not live in Downing Street. In 1675 he retired to Cambridge, where he died in 1684, a few months after building was completed. In 1800 the wealth he had accumulated was used to found Downing College, Cambridge, as had been his wish should his descendants fail in the male line. Downing's portrait hangs in the entrance hall of Number 10.


title: 10 Downing Street

text: The "House at the Back", the largest of the three houses which were combined to make Number 10, was a mansion built in about 1530 next to Whitehall Palace. Rebuilt, expanded, and renovated many times since, it was originally one of several buildings that made up the "Cockpit Lodgings", so-called because they were attached to an octagonal structure used for cock-fighting. Early in the 17th century, the Cockpit was converted to a concert hall and theatre; after the Glorious Revolution of 1688, some of the first cabinet meetings were held there secretly.


title: 10 Downing Street

text: For many years, the "House at the Back" was the home of Thomas Knevett, Keeper of Whitehall Palace, famous for capturing Guy Fawkes in 1605 and foiling his plot to assassinate King James I. The previous year, Knevett had moved into a house next door, approximately where Number 10 is today.


title: 10 Downing Street

text: From that time, the "House at the Back" was usually occupied by members of the royal family or the government. Princess Elizabeth, eldest daughter of King James I, lived there from 1604 until 1613 when she married Frederick V, Elector Palatine and moved to Heidelberg. She was the grandmother of King George I, the Elector of Hanover, who became King of Great Britain in 1714, and was the great-grandmother of King George II, who presented the house to Walpole in 1732.


title: 10 Downing Street

text: George Monck, 1st Duke of Albemarle, the general responsible for the Restoration of the Monarchy in 1660, lived there from 1660 until his death in 1671. As head of the Great Treasury Commission of 1667–1672, Albemarle transformed accounting methods and allowed the Crown greater control over expenses. His secretary, George Downing, who built Downing Street, is thought to have created these changes. Albemarle is the first treasury minister to have lived in what became the home of the First Lord of the Treasury and Prime Minister.


title: 10 Downing Street

text: In 1671 George Villiers, 2nd Duke of Buckingham took possession when he joined the Cabal Ministry. At considerable expense, Buckingham rebuilt the house. The result was a spacious mansion, lying parallel to Whitehall Palace with a view of St James Park from its garden.


title: 10 Downing Street

text: After Buckingham retired in 1676, Lady Charlotte Fitzroy, Charles II's daughter, moved in when she married Edward Lee, 1st Earl of Lichfield. The Crown authorised extensive rebuilding which included adding a storey, thus giving it three main floors, an attic and basement. This structure can be seen today as the rear section of Number 10. "(See Plan of the Premises Granted to the Earl and Countess of Lichfield in 1677)" The likely reason that repair was required is that the house had settled in the swampy ground near the Thames, causing structural damage. Like Downing Street, it rested on a shallow foundation, a design error that caused problems until 1960 when the modern Number 10 was rebuilt on deep pilings.


title: 10 Downing Street

text: The Lichfields followed James II into exile after the Glorious Revolution. Two years later in 1690, William III and Mary II gave the "House at the Back" to Hendrik van Nassau-Ouwerkerk, a Dutch general who had assisted in securing the Crown for the Prince of Orange. Nassau, who Anglicised his name to "Overkirk", lived there until his death in 1708.


title: 10 Downing Street

text: The "House at the Back" reverted to the Crown when Lady Overkirk died in 1720. The Treasury issued an order "for repairing and fitting it up in the best and most substantial manner" at a cost of £2,522. The work included: "The Back passage into Downing street to be repaired and a new door; a New Necessary House to be made; To take down the Useless passage formerly made for the Maids of Honour to go into Downing Street, when the Queen lived at the Cockpit; To New Cast a great Lead Cistern & pipes and to lay the Water into the house & a new frame for ye Cistern". "(See Buildings on the Site of the Cockpit and Number 10 Downing Street c1720)"


title: 10 Downing Street

text: The name of the "House at the Back" changed with the occupant, from Lichfield House to Overkirk House in 1690 to Bothmer House in 1720.


title: 10 Downing Street

text: Johann Caspar von Bothmer, Premier Minister of the Electorate of Hanover, head of the German Chancery and adviser to George I and II, took up residency in 1720. Although Bothmer complained about "the ruinous Condition of the Premises", he lived there until his death in 1732. Even though Count von Bothmer was not British, he was a subject of George I and George II and the first politician and head of a government who resided in 10 Downing Street.


title: 10 Downing Street

text: When Count Bothmer died, ownership of the "House at the Back" reverted to the Crown. George II took this opportunity to offer it to Robert Walpole, often called the first prime minister, as a gift for his services to the nation: stabilising its finances, keeping it at peace and securing the Hanoverian succession. Coincidentally, the King had obtained the leases on two Downing Street properties, including Number 10, and added these to his proposed gift.


title: 10 Downing Street

text: Walpole did not accept the gift for himself. He proposed—and the King agreed—that the Crown give the properties to the Office of First Lord of the Treasury. Walpole would live there as the incumbent First Lord, but would vacate it for the next one.


title: 10 Downing Street

text: To enlarge the new house, Walpole persuaded Mr Chicken, the tenant of a cottage next door, to move to another house in Downing Street. This small house and the mansion at the back were then incorporated into Number 10. Walpole commissioned William Kent to convert them into one building. Kent joined the larger houses by building a two-storey structure between them, consisting of one long room on the ground floor and several above. The remaining interior space was converted into a courtyard. He connected the Downing Street houses with a corridor.


title: 10 Downing Street

text: Having united the structures, Kent gutted and rebuilt the interior. He then surmounted the third storey of the house at the back with a pediment. To allow Walpole quicker access to Parliament, Kent closed the north side entrance from St James's Park, and made the door in Downing Street the main entrance.


title: 10 Downing Street

text: The rebuilding took three years. On 23 September 1735, the "London Daily Post" announced that: "Yesterday the Right Hon. Sir Robert Walpole, with his Lady and Family, removed from their House in St James's Square, to his new House, adjoining to the Treasury in St James's Park". The cost of conversion is unknown. Originally estimated at £8,000, the final cost probably exceeded £20,000.


title: 10 Downing Street

text: Walpole did not enter through the now-famous door; that would not be installed until forty years later. Kent's door was modest, belying the spacious elegance beyond. The First Lord's new, albeit temporary, home had sixty rooms, with hardwood and marble floors, crown moulding, elegant pillars and marble mantelpieces; those on the west side with views of St James's Park. One of the largest rooms was a study measuring forty feet by twenty with enormous windows overlooking St James's Park. "My Lord's Study" (as Kent labelled it in his drawings) would later become the Cabinet Room where Prime Ministers meet with the Cabinet ministers.


title: 10 Downing Street

text: Shortly after moving in, Walpole ordered that a portion of the land outside his study be converted into a terrace and garden. Letters patent issued in April 1736 state that: "... a piece of garden ground situated in his Majesty's park of St James's, & belonging & adjoining to the house now inhabited by the Right Honourable the Chancellor of His Majesty's Exchequer, hath been lately made & fitted up at the Charge ... of the Crown".


title: 10 Downing Street

text: The same document confirmed that Number 10 Downing Street was: "meant to be annexed & united to the Office of his Majesty's Treasury & to be & to remain for the Use & Habitation of the first Commissioner of his Majesty's Treasury for the time being".


title: 10 Downing Street

text: At about the same time that William Kent was combining the Downing Street townhouse with the house at the back, he was also commissioned to design and construct a new Treasury building on the site of the old Tudor Cockpit located behind Downing Street. This project was completed in 1737 and included corridors connecting the Treasury building with Ten Downing Street allowing Walpole, as Chancellor of the Exchequer as well as First Lord of the Treasury and Prime Minister, direct and convenient access to the Treasury offices. In effect the Treasury building became an annex of Ten Downing Street and its staff worked directly for Walpole on treasury, patronage and other public business. This arrangement remained in effect until the middle of the 19th century and until then all Prime Ministers who were also Chancellor took advantage of it. After Prime Minister Robert Peel "gave up" being Chancellor in 1841, and this separation of positions gradually became a convention of the constitution, a locked door was installed between the buildings limiting the Prime Minister's access to the Treasury and its staff. Due to bomb damage in 1940, the Treasury relocated to the Government Offices Great George Street. Then in 1963 the Cabinet Office (including the Prime Minister's Office) and later the Civil Service (with the Prime minister as Minister for the Civil Service) moved into the renovated Kent Treasury Building. "Under (Prime Minister) Blair . . . the locked door, symbolically and physically dividing No. 10 from the Cabinet Office, was passed through with such frequency that its meaning was lost."


title: 10 Downing Street

text: Walpole lived in Number 10 until 1742. Although he had accepted it on behalf of future First Lords of the Treasury, it would be 21 years before any of his successors chose to live there; the five who followed Walpole preferred their own homes. This was the pattern until the beginning of the 20th century. Of the 31 First Lords from 1735 to 1902, only 16 (including Walpole) lived in Number 10.


title: 10 Downing Street

text: One reason many First Lords chose not to live in Number 10 was that most owned London town houses superior in size and quality. To them, Number 10 was unimpressive. Their possession of the house, albeit temporary, was a perquisite they could bestow as a political reward. Most lent it to the Chancellor of the Exchequer, others to lesser officials or to friends and relatives.


title: 10 Downing Street

text: Another reason for its unpopularity was that Number 10 was a hazardous place in which to live. Prone to sinking because it was built on soft soil and a shallow foundation, floors buckled and walls and chimneys cracked. It became unsafe and frequently required repairs. In 1766, for example, Charles Townshend, Chancellor of the Exchequer, pointed out that the house was in a dilapidated condition. His architect's letter to the Treasury stated: "...we have caused the House in Downing Street belonging to the Treasury to be surveyed, & find the Walls of the old part of the said House next the street to be much decayed, the Floors & Chimneys much sunk from the level". Townshend ordered extensive repairs, which were still incomplete eight years later. A note from Lord North to the Office of Works, dated September 1774, asks that the work on the front of the house, "which was begun by a Warrant from the Treasury dated 9 August 1766", should be finished. "(See Kent's Treasury and No. 10, Downing Street, circa 1754.)"


title: 10 Downing Street

text: Treasury officials complained that the building was costing too much to maintain; some suggested that it should be razed and a new house constructed on the site or elsewhere. In 1782 the Board of Works reporting on "the dangerous state of the old part of the House", stated that "no time be lost in taking down said building". In 1783 the Duke of Portland moved out because it was once again in need of repair. A committee found that the money spent so far was insufficient. This time the Board of Works declared that "the Repairs, Alterations & Additions at the Chancellor of the Exchequer's House will amount to the sum of £5,580, exclusive of the sum for which they already have His Majesty's Warrant. And praying a Warrant for the said sum of £5,580—and also praying an Imprest of that sum to enable them to pay the Workmen". This proved to be a gross underestimate; the final bill was over £11,000. The "Morning Herald" fumed about the expense: "£500 pounds p.a. preceding the Great Repair, and £11,000 the Great Repair itself! So much has this extraordinary edifice cost the country – For one moiety of the sum a much better dwelling might have been purchased!" "(See Plan of the Design for Number 10 c1781.)"


title: 10 Downing Street

text: A few prime ministers however did enjoy living in Number 10. Lord North, who conducted the war against the American Revolution, lived there happily with his family from 1767 to 1782. William Pitt the Younger, who made it his home for twenty years (longer than any First Lord before or since) from 1783 to 1801 and from 1804 to 1806, referred to it as "My vast, awkward house". While there, Pitt reduced the national debt, formed the Triple Alliance against France and won passage of the Act of Union that created the United Kingdom of Great Britain and Ireland. Fredrick Robinson, Lord Goderich took a special liking to the house in the late 1820s and spent state funds lavishly remodelling the interior.


title: 10 Downing Street

text: Nevertheless, for 70 years following Pitt's death in 1806, Number 10 was rarely used as the First Lord's residence. From 1834 to 1877, it was either vacant or used only for offices and meetings.


title: 10 Downing Street

text: Downing Street declined at the turn of the 19th century, becoming surrounded with run-down buildings, dark alleys, the scene of crime and prostitution. Earlier, the government had taken over the other Downing Street houses: the Colonial Office occupied Number 14 in 1798; the Foreign Office was at Number 16 and the houses on either side; the West India Department was in Number 18; and the Tithe Commissioners in Number 20. The houses deteriorated from neglect, became unsafe, and one by one were demolished. By 1857 Downing Street's townhouses were all gone except for Number 10, Number 11 (customarily the Chancellor of the Exchequer's residence), and Number 12 (used as offices for Government Whips). In 1879 a fire destroyed the upper floors of Number 12; it was renovated but only as a single-storey structure. "(See Numbers 10, 11, and 12 Downing Street First Floor Plan and Ground Floor Plan.)"


title: 10 Downing Street

text: When Lord Salisbury retired in 1902, his nephew, Arthur James Balfour, became Prime Minister. It was an easy transition: he was already First Lord of the Treasury and he was already living in Number 10. Balfour revived the custom that Number 10 is the First Lord and Prime Minister's official residence. It has remained the custom since.


title: 10 Downing Street

text: However, there have been numerous times when prime ministers have unofficially lived elsewhere out of necessity or preference. Winston Churchill, for example, had a great affection for Number 10, but, during World War II, he grudgingly slept in the hastily converted flat on the ground floor of what was then the New Public Office building (NPO) at nearby Storey's Gate. The flat became known as the No.10 Annexe, and lay above the much more comprehensive underground bunker now known as the Cabinet War Rooms, and where he also had a bedroom, very rarely used. To reassure the people that his government was functioning normally, he insisted on being seen entering and leaving Number 10 occasionally, and indeed, continued to use it for meetings and dinners despite being urged not to. Harold Wilson, during his second ministry from 1974 to 1976, lived in his home in Lord North Street because Mary Wilson wanted "a proper home". However, recognizing the symbolic importance of Number 10, he worked and held meetings there and entertained guests in the State Dining Room.


title: 10 Downing Street

text: For most of his premiership, Tony Blair lived in the more spacious residence above Number 11 to accommodate his relatively large family (a wife and four children). In May 2010, it was reported that David Cameron, who also had four small children upon taking office, would also take up actual residence above Number 11, and his Chancellor, George Osborne, above Number 10.


title: 10 Downing Street

text: Despite these exceptions, Number 10 has been known as the prime minister's official home for over one hundred years. By the turn of the 20th century, photography and the penny press had linked Number 10 in the public mind with the premiership. The introduction of films and television would strengthen this association. Pictures of prime ministers with distinguished guests at the door became commonplace. With or without the prime minister present, visitors had their picture taken. Suffragettes posed in front of the door when they petitioned H. H. Asquith for women's rights in 1913, a picture that became famous and was circulated around the world. In 1931, Mohandas Gandhi, wearing the traditional homespun "dhoti", posed leaving Number 10 after meeting with Ramsay MacDonald to discuss India's independence. This picture, too, became famous especially in India. The freedom fighters could see their leader had been received in the prime minister's home. Couse's elegant, understated door—stark black, framed in cream white with a bold white "10" clearly visible—was the perfect backdrop to record such events. Prime Ministers made historic announcements from the front step. Waving the Anglo-German Agreement of Friendship, Neville Chamberlain proclaimed "Peace with honour" in 1938 from Number 10 after his meeting with Adolf Hitler in Munich. During World War II, Churchill was photographed many times emerging confidently from Number 10 holding up two fingers in the sign for "Victory". The building itself, however, did not escape the London Blitz entirely unscathed; in February 1944 a bomb fell on nearby Horse Guards Parade and some of the drawing-room windows were destroyed.


title: 10 Downing Street

text: The symbol of British government, Number 10 became a gathering place for protesters. Emmeline Pankhurst and other suffragette leaders stormed Downing Street in 1908; anti-Vietnam War protestors marched there in the 1960s, as did anti-Iraq and Afghanistan War protestors in the 2000s.


title: 10 Downing Street

text: By the middle of the 20th century, Number 10 was falling apart again. The deterioration had been obvious for some time. The number of people allowed in the upper floors was limited for fear the bearing walls would collapse. The staircase had sunk several inches; some steps were buckled and the balustrade was out of alignment. Dry rot was widespread throughout. The interior wood in the Cabinet Room's double columns was like sawdust. Skirting boards, doors, sills and other woodwork were riddled and weakened with disease. After reconstruction had begun, miners dug down into the foundations and found that the huge wooden beams supporting the house had decayed.


title: 10 Downing Street

text: In 1958, a committee under the chairmanship of the Earl of Crawford and Balcarres was appointed by Harold Macmillan to investigate the condition of the house and make recommendations. In the committee's report there was some discussion of tearing down the building and constructing an entirely new residence but because the prime minister's home had become an icon of British architecture like Windsor Castle, Buckingham Palace and the Houses of Parliament, the committee recommended that Number 10 (and Numbers 11 and 12) should be rebuilt using as much of the original materials as possible. The interior would be photographed, measured, disassembled, and restored. A new foundation with deep pilings would be laid and the original buildings reassembled on top of it, allowing for much needed expansion and modernisation. Any original materials that were beyond repair – such as the pair of double columns in the Cabinet Room – would be replicated in detail. This was a formidable undertaking: the three buildings contained over 200 rooms spread out over five floors.


title: 10 Downing Street

text: The architect Raymond Erith carried out the design for this painstaking work and the contractor that undertook it was John Mowlem & Co.


title: 10 Downing Street

text: "The Times" reported initially that the cost for the project would be £400,000. After more careful studies were completed, it was concluded that the "total cost was likely to be £1,250,000" and would take two years to complete. In the end, the cost was close to £3,000,000 and took almost three years due in large part to 14 labour strikes. There were also delays when archaeological excavations uncovered important artefacts dating from Roman, Saxon and medieval times. Macmillan lived in Admiralty House during the reconstruction.


title: 10 Downing Street

text: The new foundation was made of steel-reinforced concrete with pilings sunk . The "new" Number 10 consisted of about 60% new materials; the remaining 40% was either restored or replicas of originals. Many rooms and sections of the new building were reconstructed exactly as they were in the old Number 10. These included: the garden floor, the door and entrance foyer, the stairway, the hallway to the Cabinet Room, the Cabinet Room, the garden and terrace, the Small and Large State Rooms and the three reception rooms. The staircase, however, was rebuilt and simplified. Steel was hidden inside the columns in the Pillared Drawing Room to support the floor above. The upper floors were modernised and the third floor extended over Numbers 11 and 12 to allow more living space. As many as 40 coats of paint were stripped from the elaborate cornices in the main rooms revealing details unseen for almost 200 years in some cases.


title: 10 Downing Street

text: When builders examined the exterior façade, they discovered that the black colour visible even in photographs from the mid-19th century was misleading; the bricks were actually yellow. The black appearance was the product of two centuries of pollution. To preserve the 'traditional' look of recent times, the newly cleaned yellow bricks were painted black to resemble their well-known appearance. The thin tuckpointing mortar between the bricks is not painted, and so contrasts with the bricks.


title: 10 Downing Street

text: Although the reconstruction was generally considered an architectural triumph, Erith was disappointed. He complained openly during and after the project that the government had altered his design to save money. "I am heart broken by the result," he said. "The whole project has been a frightful waste of money because it just has not been done properly. The Ministry of Works has insisted on economy after economy. I am bitterly disappointed with what has happened." Erith described the numbers on the front, intended to be based on historical models, as 'a mess' and 'completely wrong' to a fellow historian.


title: 10 Downing Street

text: Erith's concerns proved justified. Within a few years, dry rot was discovered, especially in the main rooms due to inadequate waterproofing and a broken water pipe. Extensive reconstruction again had to be undertaken in the late 1960s to resolve these problems. Further extensive repairs and remodelling, commissioned by Margaret Thatcher, were completed in the 1980s under the direction of Erith's associate, Quinlan Terry.


title: 10 Downing Street

text: The work done by Erith and Terry in the 1960s and 1980s represent the most extensive remodelling of Number 10 in recent times. Since 1990 when the Terry reconstruction was completed, repairing, redecorating, remodelling, and updating the house has been ongoing as needed. The IRA mortar attack in February 1991 led to extensive work being done to repair the damage (mostly to the garden and exterior walls) and to improve security. In the summer of 1993 windows were rebuilt and in 1995 computer cables installed. In 1997, the building was remodelled to provide extra space for the prime minister's greatly increased staff.


title: 10 Downing Street

text: To accommodate their large families, both Tony Blair and David Cameron chose to live in the private residence above Number 11 rather than the smaller one above Number 10. In 2010, the Camerons completely modernised the 50-year-old private kitchen in Number 11. In March 2020, Prime Minister Boris Johnson refurbished the residential apartment at Number 11. This became the subject of public controversy, and an Electoral Commission inquiry took place into the financing of the refurbishment.


title: 10 Downing Street

text: The current tenant of 10 Downing Street is Prime Minister Rishi Sunak. It has been common practice in recent decades for the Prime Minister to live at Number 11, as its residential apartment is larger, and for the Chancellor to live at Number 10. However, the traditional residencies have not changed in official terms.


title: 10 Downing Street

text: It presently houses the UK Cabinet Room in which Cabinet meetings in the UK take place, chaired by the current Prime Minister, Sunak. It also houses the Prime Minister's Executive Office, which deals with logistics and diplomacy concerning the government of the United Kingdom.


title: 10 Downing Street

text: Number 10's door is the product of the renovations Charles Townshend ordered in 1766; it was probably not completed until 1772. Executed in the Georgian style by the architect Kenton Couse, it is unassuming and narrow, consisting of a single white stone step leading to a modest brick front. The small, six-panelled door, originally made of black oak, is surrounded by cream-coloured casing and adorned with a semicircular fanlight window. Painted in white, between the top and middle sets of panels, is the number "10". The zero of the number "10" is painted in a very eccentric style, in a 37° angle anticlockwise. One theory is that this is in fact a capital 'O' as found in the Roman's Trajan alphabet that was used by the Ministry of Works at the time. A black iron knocker in the shape of a lion's head is between the two middle panels; below the knocker is a brass letter box with the inscription "First Lord of the Treasury". The doorbell is inscribed with "PUSH" although is rarely used in practice. A black ironwork fence with spiked newel posts runs along the front of the house and up each side of the step to the door. The fence rises above the step into a double-swirled archway, supporting an iron gas lamp surmounted by a crown. "(See The Entrance Door c1930: As seen from the outside)" The door cannot be opened from the outside; there is always someone inside to unlock the door.


title: 10 Downing Street

text: After the IRA mortar attack in 1991, the original black oak door was replaced by a blast-proof steel one. Regularly removed for refurbishment and replaced with a replica, it is so heavy that it takes eight men to lift it. The brass letterbox still bears the legend "First Lord of the Treasury". The original door was put on display in the Churchill Museum at the Cabinet War Rooms.


title: 10 Downing Street

text: Beyond the door, Couse installed black and white marble tiles in the entrance hall that are still in use. A guard's chair designed by Chippendale sits in one corner. Once used when policemen sat on watch outside in the street, it has an unusual "hood" designed to protect them from the wind and cold and a drawer underneath where hot coals were placed to provide warmth. Scratches on the right arm were caused by their pistols rubbing up against the leather. Number 10 Downing Street has a lift.


title: 10 Downing Street

text: Couse also added a bow front to the small cottage—formerly Mr Chicken's house—incorporated into Number 10 in Walpole's time. "(See The Entrance Door c1930: As seen from inside showing the black and white marble floor and the door providing access to Number 11)"


title: 10 Downing Street

text: When William Kent rebuilt the interior between 1732 and 1734, his craftsmen created a stone triple staircase. The main section had no visible supports. With a wrought iron balustrade, embellished with a scroll design, and mahogany handrail, it rises from the garden floor to the third floor. Kent's staircase is the first architectural feature visitors see as they enter Number 10. Black and white engravings and photographs of all the past prime ministers decorate the wall. They are rearranged slightly to make room for a photograph of each new Prime Minister. There is one exception. Winston Churchill is represented in two photographs. At the bottom of the staircase are group photographs of Prime Ministers with their Cabinet ministers and representatives to imperial conferences. (See The Main Stairway c1930 General view showing portraits of the prime ministers and Detail of the Wrought Iron Balustrade) (See also Simon Schama's Tour of Downing Street. Pt4: The Staircase)


title: 10 Downing Street

text: In Kent's design for the enlarged Number 10, the Cabinet Room was a simple rectangular space with enormous windows. As part of the renovations begun in 1783, it was extended, giving the space its modern appearance. Probably not completed until 1796, this alteration was achieved by removing the east wall and rebuilding it several feet inside the adjoining secretaries' room. At the entrance, a screen of two pairs of Corinthian columns was erected (to carry the extra span of the ceiling) supporting a moulded entablature that wraps around the room. Robert Taylor, the architect who executed this concept, was knighted on its completion. The resulting small space, framed by the pillars, serves as an anteroom to the larger area. Hendrick Danckerts' painting "The Palace of Whitehall" (shown at the beginning of this article) usually hangs in the ante-room. It also contains two large bookcases that house the prime minister's library; Cabinet members traditionally donate to the collection on leaving office – a tradition that began with Ramsay MacDonald in 1931.


title: 10 Downing Street

text: Although Kent intended the First Lord to use this space as his study, it has rarely served that purpose; it has almost always been the Cabinet Room. There have been a few exceptions. Stanley Baldwin used the Cabinet Room as his office. A few prime ministers, such as Tony Blair, occasionally worked at the Cabinet Room table. Painted off-white with large floor to ceiling windows along one of the long walls, the room is light and airy. Three brass chandeliers hang from the high ceiling. The Cabinet table, purchased during the Gladstone era, dominates the room. The modern boat-shaped top, introduced by Harold Macmillan in the late 1950s, is supported by huge original oak legs. The table is surrounded by carved, solid mahogany chairs that also date from the Gladstone era. The prime minister's chair, the only one with arms, is situated midway along one side in front of the marble fireplace, facing the windows; when not in use, it is positioned at an angle for easy access. The only picture in the room is a copy of a portrait of Robert Walpole by Jean-Baptiste van Loo hanging over the fireplace. Each Cabinet member is allocated a chair based on order of seniority. Blotters inscribed with their titles mark their places.


title: 10 Downing Street

text: The First Lord has no designated office space in Number 10; each has chosen one of the adjoining rooms as his or her private office.


title: 10 Downing Street

text: Number 10 has three inter-linked state drawing rooms: the Pillared Drawing Room, the Terracotta Drawing Room and the White Drawing Room. (See the three state drawing rooms.)


title: 10 Downing Street

text: The largest is the Pillared Room thought to have been created in 1796 by Taylor. Measuring long by wide, it takes its name from the twin Ionic pilasters with straight pediments at one end. Today, there is a portrait of Queen Elizabeth I over the fireplace; during the Thatcher Ministry (1979–1990), a portrait of William Pitt by Romney was hung there.


title: 10 Downing Street

text: A Persian carpet covers almost the entire floor. A copy of a 16th-century original now kept in the Victoria and Albert Museum, there is an inscription woven into it that reads: "I have no refuge in the world other than thy threshold. My head has no protection other than this porchway. The work of a slave of the holy place, Maqsud of Kashan in the year 926" (the Islamic year corresponding to 1520).


title: 10 Downing Street

text: In the restoration conducted in the late 1980s, Quinlan Terry restored the fireplace. Executed in the Kentian style, the small Ionic pilasters in the over-mantel are miniature duplicates of the large Ionic pillars in the room. The Ionic motif is also found in the door surrounds and panelling.


title: 10 Downing Street

text: Sparsely furnished with a few chairs and sofas around the walls, the Pillared Room is usually used to receive guests before they go into the State Dining Room. However, it is sometimes used for other purposes that require a large open space. International agreements have been signed in this room. Tony Blair entertained the England Rugby Union team in the Pillared Room after they won the World Cup in 2003. John Logie Baird gave Ramsay MacDonald a demonstration of his invention, the television, in this room. "(See The Pillared Drawing Room c1927)". After the Apollo 11 lunar landing in July 1969, Harold Wilson hosted a reception in the room for astronauts Neil Armstrong, Buzz Aldrin and Michael Collins, in addition to Cambridge scientist Francis Thomas Bacon, inventor of the alkaline fuel cell used to generate power for space capsules.


title: 10 Downing Street

text: The Terracotta Room is the middle of the three drawing rooms. It was used as the dining room when Robert Walpole was prime minister. The name changes according to the colour it is painted. When Margaret Thatcher came to power it was the Blue Room; she had it re-decorated and renamed the Green Room. It is now painted terracotta.


title: 10 Downing Street

text: In the renovation of the 1980s Quinlan Terry introduced large Doric order columns to this room in the door surrounds and designed a very large Palladian overmantel for the fireplace with small double Doric columns on each side with the royal arms above. Terry also added an ornate gilded ceiling to give the rooms a more stately look. Carved into the plasterwork above the door leading to the Pillared Room is a tribute to Margaret Thatcher: a straw-carrying 'thatcher'.


title: 10 Downing Street

text: The White State Drawing room was, until the 1940s, used by Prime Ministers and their partners for their private use. It was here that Edward Heath kept his grand piano. It is often used as the backdrop for television interviews and is in regular use as a meeting room for Downing Street staff. The room links through to the Terracotta Room next door. In the reconstruction during the late 1980s, Quinlan Terry used Corinthian columns and added ornate Baroque-style central ceiling mouldings and corner mouldings of the four national flowers of the United Kingdom: rose (England), thistle (Scotland), daffodil (Wales) and shamrock (Northern Ireland).


title: 10 Downing Street

text: When Frederick Robinson (later Lord Goderich), became Chancellor of the Exchequer in 1823, he decided to leave a personal legacy to the nation. To this end, he employed John Soane, the distinguished architect who had designed the Bank of England and many other famous buildings, to build a State Dining Room for Number 10. Begun in 1825 and completed in 1826 at a cost of £2,000, the result is a spacious room with oak panelling and reeded mouldings. Accessed through the first floor, its vaulted, arched ceiling rises up through the next so that it actually occupies two floors. Measuring , it is the largest room in Number 10. Soane was the guest of honour when the dining room was first used on 4 April 1826.


title: 10 Downing Street

text: The room is usually furnished with a table surrounded by 20 reproduction Adam style chairs originally made for the British Embassy in Rio de Janeiro. For larger gatherings, a horseshoe-shaped table is brought in that will accommodate up to 65 guests. On these occasions, the table is set with the Silver Trust Silver set given to Downing Street in the 1990s. (See the State Dining room with the Silver Trust Silver in use for a luncheon) Above the fireplace, overlooking the room, is a massive portrait by John Shackleton of George II, the king who originally gave the building to the First Lord of the Treasury in 1732. Celebrity chefs such as Nigella Lawson have cooked for Prime Ministers' guests using the small kitchen next door. Entering through the Small Dining Room, Blair used this room for his monthly press conferences. (See Simon Schama's Tour of Downing Street. Pt 3: The Dining Room)


title: 10 Downing Street

text: The great kitchen located in the basement was another part of the renovations begun in 1783, probably also under the direction of Robert Taylor. Seldom seen by anyone other than staff, the space is two storeys high with a huge arched window and vaulted ceiling. Traditionally, it has always had a chopping block work table in the centre that is long, wide and thick.


title: 10 Downing Street

text: Above Taylor's vaulted kitchen, between the Pillared Room and the State Dining room, Soane created a Smaller Dining Room (sometimes called the Breakfast Room) that still exists. To build it, Soane removed the chimney from the kitchen to put a door in the room. He then moved the chimney to the east side, running a Y-shaped split flue inside the walls up either side of one of the windows above. The room therefore has a unique architectural feature: over the fireplace there is a window instead of the usual chimney breast.


title: 10 Downing Street

text: With its flat unadorned ceiling, simple mouldings and deep window seats, the Small Dining Room is intimate and comfortable. Usually furnished with a mahogany table seating only eight, Prime Ministers have often used this room when dining with family or when entertaining special guests on more personal state occasions. "(See the Small Dining or Breakfast Room c1927. The double doors behind the table lead to the State Dining Room.)"


title: 10 Downing Street

text: The terrace and garden were constructed in 1736 shortly after Walpole moved into Number 10. The terrace, extending across the back, provides a full view of St James's Park. The garden is dominated by a half-acre (0.2 ha) open lawn which wraps around Numbers 10 and 11 in an L-shape. No longer "fitted with variety Walle fruit and diverse fruit trees" as it was in the 17th century, there is now a centrally located flower bed around a holly tree surrounded by seats. Tubs of flowers line the steps from the terrace; around the walls are rose beds with flowering and evergreen shrubs. (See North elevation of Number 10 with steps leading to the garden) The terrace and garden have provided a casual setting for many gatherings of First Lords with foreign dignitaries, Cabinet ministers, guests, and staff. Prime Minister Tony Blair, for example, hosted a farewell reception in 2007 for his staff on the terrace. John Major announced his 1997 resignation as leader of the Conservative Party in the garden. Churchill called his secretaries the "garden girls" because their offices overlook the garden. It was also the location of the first press conference announcing the Coalition Government between David Cameron's Conservatives and Nick Clegg's Liberal Democrats.


title: 10 Downing Street

text: Number 10 is filled with fine paintings, sculptures, busts and furniture. Only a few are permanent features. Most are on loan. About half belong to the Government Art Collection. The remainder are on loan from private collectors and from public galleries such as the National Portrait Gallery, the Tate Gallery, the Victoria and Albert Museum and the National Gallery. (See works from the Government Art Collection currently on display at Number 10)


title: 10 Downing Street

text: About a dozen paintings are changed annually. More extensive changes occur when a new Prime Minister takes office and redecorates. These redecorations may reflect both individual taste as well as make a political statement. Edward Heath borrowed French paintings from the National Gallery and was loaned two Renoirs from a private collector. When Margaret Thatcher arrived in 1979 she insisted that the artwork had to be British and that it celebrate "British achievers". As a former chemist, she took pleasure in devoting the Small Dining Room to a collection of portraits of British scientists, such as Joseph Priestley and Humphry Davy. During the 1990s John Major converted the first floor anteroom into a small gallery of modern art, mostly British. He also introduced several paintings by John Constable and J. M. W. Turner, Britain's two best known 19th-century artists, and cricketing paintings by Archibald Stuart-Wortley including a portrait of one of England's most celebrated batsmen W. G. Grace.


title: 10 Downing Street

text: In addition to outstanding artwork, Number 10 contains many exceptional pieces of furniture either owned by the house or on loan. One of the most striking and unusual is the already mentioned Chippendale hooded guard's chair that sits in a corner of the entrance hall. To its left is a long case clock by Benson of Whitehaven. A similar clock by Samuel Whichcote of London stands in the Cabinet anteroom. The White State Drawing Room contains examples of Adam furniture. The Green State Drawing Room contains mostly Chippendale furniture including a card table that belonged to Clive of India and a mahogany desk that is thought to have belonged to William Pitt the Younger and used by him during the Napoleonic Wars. In addition to the large carpet previously described, the Pillared State Drawing Room also contains a marble-topped table by Kent. The State Dining Room contains a mahogany sideboard by Adam. Until the late 19th century, Prime Ministers were required to furnish Number 10 at their own expense with furniture, tableware, china, linens, curtains and decorations. This arrangement began to change in 1877 when Benjamin Disraeli took up residency. He insisted that the Treasury should bear the cost of furnishings at least in the public areas. The Treasury agreed and a complex accounting procedure was developed whereby the outgoing prime minister was required to pay for "wear and tear" on furnishings that had been purchased by the Treasury. This system was used until November 1897 when the Treasury assumed responsibility for purchasing and maintaining almost all of the furnishings in both the public and private areas except decorating the walls with art work. In 1924 when Prime Minister Ramsay MacDonald took office, he did not own nor have the means to buy an extensive art collection. He had the Government Art Collection loan pieces. The arrangement became the standard practice.


title: 10 Downing Street

text: In 1985, Number 10 was 250 years old. To celebrate, Thatcher hosted a grand dinner in the State Dining Room for her living predecessors: Harold Macmillan, Alec Douglas-Home, Harold Wilson, Edward Heath and James Callaghan. Also in attendance were Elizabeth II and representatives of the families of every 20th-century Prime Minister since H. H. Asquith, including Lady Olwen Carey Evans (daughter of David Lloyd George), Lady Leonora Howard (daughter of Stanley Baldwin), and Clarissa Avon (widow of Anthony Eden and niece of Winston Churchill).


title: 10 Downing Street

text: That same year, the Leisure Circle published Christopher Jones' book "No. 10 Downing Street, The Story of a House". In the foreword, Thatcher described her feelings for Number 10: "How much I wish that the public ... could share with me the feeling of Britain's historic greatness which pervades every nook and cranny of this complicated and meandering old building ... All Prime Ministers are intensely aware that, as tenants and stewards of No. 10 Downing Street, they have in their charge one of the most precious jewels in the nation's heritage".


title: 10 Downing Street

text: For most of its history, Number 10 was accessible to the public. Early security consisted of two police officers: one stood guard outside the door; the other was stationed inside to open it. Since the door had no keyhole, the inside officer depended upon the lone outside officer. During Thatcher's premiership, terrorist threats led to the implementation of a second level of security. Guarded gates were added at both ends of the street. Visitors could then be screened before approaching the door.


title: 10 Downing Street

text: Despite the added measure, on 7 February 1991, the Provisional IRA used a van they parked in Whitehall to launch a mortar shell at Number 10. It exploded in the back garden, while Prime Minister John Major was holding a Cabinet meeting. Major moved to Admiralty House while repairs were being completed. This led to the addition of guardhouses at the street ends as well as other less visible measures. Each guardhouse is staffed by several armed police officers. The Metropolitan Police Service's Diplomatic Protection Group (DPG) provides overall protection and acts on intelligence from MI5.


title: 10 Downing Street

text: The Prime Minister's Office, for which the terms "Downing Street" and "Number 10" are metonymous, lies within the 10 Downing Street building and is part of the Cabinet Office. It is staffed by a mix of career civil servants and special advisers. The highest ranking civil servant position is the principal private secretary to the prime minister, Nick Catsaras. From 2010 to 2012 and from May to September 2020, there was a Downing Street Permanent Secretary, held by Jeremy Heywood and Simon Case respectively, which ranked above the principal private Secretary to the prime minister. From 1997 to 2019 and since 2020, the most senior special adviser post is the Downing Street chief of staff but this job title was out of use from July 2019 to November 2020 when the role was split into two positions with Dominic Cummings who served as the chief adviser to the prime minister, and Edward Lister who served as the chief strategic adviser to the prime minister. Lister served as acting chief of staff, but was replaced by Dan Rosenfield, who officially assumed the role in January 2021. Though Number 10 is formally part of the Cabinet Office, it reports directly to the Cabinet Secretary, who is Simon Case.


title: 10 Downing Street

text: In her report about parties on Government premises during the COVID pandemic, Sue Gray concluded that the size of the Downing Street operation had increased without the structures to support them, and "too much responsibility and expectation is placed on the senior official whose principal function is ... support of the Prime Minister". She said this needed to be addressed as a priority, and Boris Johnson agreed to the Office of the Prime Minister becoming a Government department. Several changes in staffing took place early in February 2022. The role of Downing Street Permanent Secretary was revived, with Samantha Jones holding the position on an interim basis.
