Tiananmen 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. At the north end of the Square is Tiananmen Tower. Initially built in 1417 during the Ming Dynasty (1368 A.D.- 1644 A.D.), the Square was the front door of the Forbidden City. The most important use of it in the past was to declare in a big ceremony to the common people who became the emperor and who became the empress. Tian'anmen square is named after its magnificent Tiananmen Rostrum (Gate of Heavenly Peace), which was the first gate of the Imperial City. Tiananmen Square has great cultural significance as a symbol because it was the site of several key events in Chinese history. Tiananmen Square is in the center of Beijing City, which said to be the largest square in the world. It is the symbol of the Peoples Republic. Tiananmen Square covers an area of approximately 440,000 square meters with 500 meters in width and 880meters in length. That means it could hold maximum of a million people at one time. Tiananmen Square is surrounded by Tiananmen Tower, Great Hall of People, Monument to the Peoples Heroes, Chairman Mao Memorial Hall and Chinese National Museum. In a large degree, they all could be treated as the compositions of the Tiananmen Square. Now Tiananmen Square is one of the most famous and popular places in China. It is the place for celebrations on such festive days as International Labor Day on May 1 and National Day on October 1. Tian'anmen Square had completed its renovation to welcome the 50th anniversary of China in 1999.
