人民英雄纪念碑
In 1954, the Gate of China was demolished, allowing for the enlargement of the square. In November 1958, a major expansion of Tiananmen Square started, which was completed after only 11 months, in August 1959. This followed the vision of Mao Zedong to make the square the largest and most spectacular in the world, and intended to hold over 500,000 people. In that process, a large number of residential buildings and other structures have been demolished. On its southern edge, the Monument to the People's Heroes has been erected. Concomitantly, as part of the Ten Great Buildings constructed between 1958 and 1959 to commemorate the ten-year anniversary of the People's Republic of China (PRC), the Great Hall of the People and the Revolutionary History Museum (now the National Museum of China) were erected on the western and eastern sides of the square.
