Golden Horn

The Golden Horn (; , Chrysókeras; ), also known by its modern Turkish name,  (), is a major urban waterway and the primary inlet of the Bosphorus in Istanbul, Turkey.

As a natural estuary that connects with the Bosphorus Strait at the point where the strait meets the Sea of Marmara, the waters of the Golden Horn help define the northern boundary of the peninsula constituting "Old Istanbul" (ancient Byzantium and Constantinople), the tip of which is the promontory of Sarayburnu, or Seraglio Point. This estuarial inlet geographically separates the historic center of Istanbul from the rest of the city, and forms a horn-shaped, sheltered harbor that in the course of history has  protected Greek, Roman, Byzantine, Ottoman and other maritime trade ships for thousands of years.

While the reference to a "horn" is understood to refer to the inlet's aerial silhouette, the significance of the designation "golden" remains more obscure, with historians believing it to refer to either the riches brought into the city through the bustling historic harbor located along its shores, or to romantic artistic interpretations of the rich yellow light blazing upon the estuary's waters as the sun sets over the city. Its Greek and English names mean the same, while its Turkish name,  Haliç, simply means "estuary", and derives from the Arabic word  khaleej, meaning  "gulf".

Throughout its storied past, the Golden Horn has witnessed many tumultuous historical incidents, and numerous works of art have depicted its dramatic vistas.

Description

The Golden Horn is the estuary of the Alibeyköy and Kağıthane Rivers. It is 7.5 kilometers (4.66 mi) long, and 750 meters (2,460 ft) across at its widest. Its maximum depth, where it flows into the Bosphorus, is about 35 meters (115 ft).

At present, the Golden Horn is spanned by five bridges. Moving from upstream to downstream (i.e. northwest to southeast), these are as follows:

 Haliç Bridge, completed in 1974, which connects the neighborhoods of Sütlüce and Defterdar
 Eski Galata Bridge (literally, Old Galata Bridge), now-defunct, which used to connect the downstream neighborhoods of Karaköy and Eminönü, but was disassembled and relocated upstream between Ayvansaray and Keçeci Piri following extensive damage in 1992 caused by a fire originating in the kitchen of one of the restaurants located on the bridge's lower level. Originally dating back to 1912, the now-retired structure is no longer used for vehicular or pedestrian traffic, but functions as a seasonal outdoor exhibit and event space attached to Haliç Park.
 Atatürk Bridge, aka Unkapanı Bridge, completed in 1940, which connects Kasımpaşa and Unkapanı 
 Golden Horn Metro Bridge, a pedestrianized railway crossing, completed in 2014, that extends subway line M2 of the Istanbul Metro across the Golden Horn 
 Galata Bridge (its fifth incarnation, completed in 1994), between Karaköy and Eminönü

History

Archaeological records show a significant urban presence on and around the Golden Horn dating back to at least the 7th century BC, with smaller settlements going as far back as 6700 BC as confirmed by recent discoveries of ancient ports, storage facilities, and fleets of trade ships unearthed during the construction works of the Yenikapı subway station and the Marmaray tunnel project.

Indeed, the deep natural harbor provided by the Golden Horn has always been a major economic attraction and strategic military advantage for inhabitants of the area, and the Eastern Roman colonizers that established Nova Roma along its shores, which became, in order, Byzantium, Constantinople, and ultimately, Istanbul, were no different.

The Byzantine Empire had its naval headquarters there, and walls were built along the shoreline to protect the city of Constantinople from naval attacks. At the entrance to the Horn on the northern side, a large chain was pulled across from Constantinople to the old Tower of Galata to prevent unwanted ships from entering.  Known among the Byzantines as the Megàlos Pyrgos (meaning "Great Tower" in Greek), this tower was largely destroyed by the Latin Crusaders during the Fourth Crusade in 1204. In 1348, the Genoese built a new tower nearby which they called Christea Turris (Tower of Christ), now called Galata Tower.

There were three notable times when the chain across the Horn was either broken or circumvented. In the 10th century the Kievan Rus' dragged their longships out of the Bosphorus, around Galata, and relaunched them in the Horn; the Byzantines defeated them with Greek fire. In 1204, during the Fourth Crusade, Venetian ships were able to break the chain with a ram. In 1453, Ottoman Sultan Mehmed II, having failed in his attempt to break the chain with brute force, instead used the same tactic as the Rus'; towing his ships across Galata over greased logs and into the estuary.

After the Ottoman conquest of Constantinople in 1453, Mehmed II resettled ethnic Greeks along the Horn in the Phanar (today's Fener). Balat continued to be inhabited by Jews, as during the Byzantine age, though many Jews decided to leave following the takeover of the city. This area was repopulated when Bayezid II invited the Jews who were expelled from Spain to resettle in Balat.

In 1502, Leonardo da Vinci produced a drawing of a single-span  bridge over the Golden Horn as part of a civil engineering project for Sultan Bayezid II. Leonardo's drawings and notes regarding this bridge are currently displayed at the Museo della Scienza e della Tecnologia in Milan, Italy. While the original design was never executed, the vision of Leonardo's Golden Horn Bridge was resurrected in 2001, when a small footbridge based on Leonardo's design was constructed near Ås in Norway by Vebjørn Sand.

Until the 1980s, the Horn was polluted with industrial waste from the factories, warehouses, and shipyards along its shores. It has since been cleaned, and the local fish, wildlife, and flora have been largely restored.

Nowadays, the Golden Horn is settled on both sides, and there are parks along each shore. The Istanbul Chamber of Commerce is also located along the shore, as are several Muslim, Jewish and Christian cemeteries. Other institutions along the Horn's banks include museums, congress and cultural halls, supporting facilities of the Turkish Navy, and campuses of various universities.

Today, the Horn's history and natural environment make it a popular tourist attraction in Istanbul, visited by 10 million international vacationers annually.

In popular culture
The Golden Horn is featured in many works of literature dealing with classical themes.  For example, G. K. Chesterton's poem Lepanto contains the memorable couplet "From evening isles fantastical rings faint the Spanish gun, / And the Lord upon the Golden Horn is laughing in the sun."
