About the Gate of Supreme Harmony (Forbidden City)
The Gate of Supreme Harmony is the second major gate on the southern side of Beijing's Forbidden City in China. The gate dates originally to the Ming dynasty, when it was known as Fengtianmen. After the Manchu conquest of China, it received new Chinese and Manchu names. In 1886 it burned down after a lamp tipped over in the guard room and started a fire. The gate that stands there dates from the rebuilding that followed, finished in 1894.
During the Ming dynasty the Emperor met his ministers at the gate for morning court sessions about state affairs, though for most of that period the sessions were purely ceremonial. They showed the Emperor's diligence and the standing of the titular first minister. Under the Qing dynasty the Emperor attended court far more often, and the morning sessions took place at the Gate of Heavenly Purity, much nearer his living quarters. This gate also hosted banquets and other ceremonies on occasion.
The gate is seven bays wide and three bays deep, and it covers 1,371.4 m² (14,762 sq ft) in all. Two minor gates stand beside it: Zhendu Gate on its west and Zhaode Gate on its east. Together with the Meridian Gate it bounds a great plaza on the north and south. A winding waterway named Inner River of the Golden Water crosses the plaza, and five bridges span it. To the north lies Harmony Square, leading to the Hall of Supreme Harmony, the ceremonial center of the Forbidden City.
