TIAN'ANMEN SQUARE - Tian'anmen Square is the large plaza near the center of Beijing, China, named after the Tiananmen (literally, Gate of Heavenly Peace) which sits to its north, separating it from the Forbidden City. It has great cultural significance as a symbol because it was the site of several key events in Chinese history (See below: Events). Outside of China, the square is best known for the Tiananmen Square Protests of 1989.

The square is 880 meters south to north and 500 meters east to west, a total area of 440,000 square meters, which makes it the largest open-urban square in the world – considerably larger than Red Square in Moscow.

The Tiananmen was built in 1417. In 1699 (early Qing Dynasty), the Tiananmen was renovated and renamed to its present form. During the Ming and Qing eras, there was no public square at Tiananmen, and instead the area was filled with offices for imperial ministries. These were badly damaged during the Boxer Rebellion and the area was cleared to produce the beginning of Tiananmen Square.

Enlarged in 1949 to the current size, its flatness is broken only by the 38 meter high Monument to the People's Heroes and the Mausoleum of Mao Zedong. The square lies between two ancient, massive gates: the Tian'anmen 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. 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 huge lampposts which also sport video cameras. It is heavily monitored by uniformed and plain clothes policemen.

Tiananmen Square has been the site of a number of political events such as the proclamation of the People's Republic of China by Mao Zedong in October 1, 1949 and for mass rallies during the Cultural Revolution. It has also been the site of a number of protest movements, most notably the May Fourth Movement of 1919 for science and democracy, protests in 1976 after the death of Zhou Enlai, and the Tiananmen Square protests of 1989.
