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. 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 widely known for the Tiananmen Square protests of 1989.

The square is 880 meters (2887 feet) south to north and 500 meters (1640 feet) east to west, a total area of 440,000 square meters (108.7 acres), which makes it the largest open-urban square in the world.
