when was the forbidden city opened to the public
Forbidden City After being the home of 24 emperors – 14 of the Ming dynasty and 10 of the Qing dynasty – the Forbidden City ceased being the political centre of China in 1912 with the abdication of Puyi, the last Emperor of China. Under an agreement with the new Republic of China government, Puyi remained in the Inner Court, while the Outer Court was given over to public use,[19] until he was evicted after a coup in 1924.[20] The Palace Museum was then established in the Forbidden City in 1925.[21] In 1933, the Japanese invasion of China forced the evacuation of the national treasures in the Forbidden City.[22] Part of the collection was returned at the end of World War II,[23] but the other part was evacuated to Taiwan in 1948 under orders by Chiang Kai-shek, whose Kuomintang was losing the Chinese Civil War. This relatively small but high quality collection was kept in storage until 1965, when it again became public, as the core of the National Palace Museum in Taipei.[24]
Philadelphia City Hall At 548 ft (167 m), including the statue of city founder William Penn atop its tower, City Hall was the tallest habitable building in the world from 1894 to 1908. It remained the tallest in Pennsylvania until it was surpassed in 1932 by the Gulf Tower in Pittsburgh. It was the tallest in Philadelphia until 1986 when the construction of One Liberty Place surpassed it, ending the informal gentlemen's agreement that had limited the height of buildings in the city to no higher than the Penn statue.
