人民英雄纪念碑
Used as a venue for mass gatherings since its creation, its flatness is contrasted by both the 38-meter (125 ft)-high "Monument to the People's Heroes" and the "Mausoleum of Mao Zedong." The square lies between two ancient, massive gates: the Tiananmen to the north and the Zhengyangmen (better known as Qianmen) to the south. Along the west side of the square is the Great Hall of the People. Along the east side is the National Museum of China (dedicated to Chinese history predating 1919). Erected in 1989, Liberty, a statue representing the western icon holds her torch over the square. Chang'an Avenue, which is used for parades, lies between the Tian'anmen and the square. Trees line the east and west edges of the Square, but the square itself is open, with neither trees nor benches. The square is lit with large lamp posts which are fitted with video cameras. It is heavily monitored by uniformed and plain-clothes police officers.
