building To the south of the Forbidden City

To the south, two nearly identical gatehouses stand along the main axis. They are the Upright Gate (Chinese: 端门; pinyin: Duānmén) and the more famous Tiananmen Gate, which is decorated with a portrait of Mao Zedong in the centre and two placards to the left and right: "Long Live the People's Republic of China" and "Long live the Great Unity of the World's Peoples". The Tiananmen Gate connects the Forbidden City precinct with the modern, symbolic centre of the Chinese state, Tiananmen Square.

While development is now tightly controlled in the vicinity of the Forbidden City, throughout the past century uncontrolled and sometimes politically motivated demolition and reconstruction has changed the character of the areas surrounding the Forbidden City. Since 2000, the Beijing municipal government has worked to evict governmental and military institutions occupying some historical buildings, and has established a park around the remaining parts of the Imperial City wall. In 2004, an ordinance relating to building height and planning restriction was renewed to establish the Imperial City area and the northern city area as a buffer zone for the Forbidden City. In 2005, the Imperial City and Beihai (as an extension item to the Summer Palace) were included in the shortlist for the next World Heritage Site in Beijing.
