梁思成
During the 20th century, some pagodas in Beijing were destroyed by war, particularly during the Second Sino-Japanese War (1937–1945). After the founding of the People's Republic of China in 1949, a new era of modernization threatened the survival many ancient buildings and structures in Beijing. Despite the vocal protests of the architect Liang Sicheng, a pair of famous pagodas in the centre of the city (the twin pagodas of Qingshou Temple), built during the Yuan dynasty, were demolished in 1954 so that Chang'an Avenue could be enlargened.
