天安门 (Wen Shien)

The Tian An Men or Gate of National Heaven is a famous monument in Beijing, the capital of China.It is widely used as a national symbol. First built during the Ming Dynasty in 1420, Tiananmen is often referred to as the front entrance to the Forbidden City. However, the Merdian Gate is the first entrance to the Forbidden City proper, while Tiananmen was the entrance to the Imperial City, within which the Forbidden City was located. Tiananmen is located to the north of Tiananmen Square, across the street from the plaza from Chang'an avenue. 

The gate was originally named Chengtianmen  or "Gate of Accepting Heaven Mandate", and it has been destroyed and rebuilt several times. The original building was first constructed in 1420 and was based on a gate of an imperial building in Nanjing with the same name and hence inherited the name Chengtianmen. The gate was damaged by lightning in July, 1457, and was completely burnt down. In 1465, Chenghua Emperor ordered the minister of Engineering Ministry to rebuild the gate, and the design was changed from the original paifang form to the gatehouse that is seen today. It suffered another blow in the war at the end of Ming Dynasty - in 1644 the gate was burnt down by rebels led by Li ZiCheng.Following the establishment of the Qing Dyansty and the Manchu  conquest of Chna proper, the gate was once again rebuilt, beginning in 1645, and was given its present name in 1651 when the construction completed six years later. The Tiananmen gate was reconstructed again between 1969-1970. The gate as it stood was by then 300 years old, and had badly deteriorated, partly due to heavy usage in the 1950s-60s. As the gate was a national symbol, then-Premier Zhou Enlai ordered that the rebuilding was to be kept secret. The whole gate was covered in scaffolding, and the project was officially called a "renovation". The rebuilding aimed to leave the gate's external appearance unchanged while making it more resistant to earthquakes and featuring modern facilities such as an elevator, water supply and heating system.
