Yingtianmen

Yingtianmen is the place where the imperial court held ceremonies such as enthronement, Yuan Dynasty reform, amnesty, banquets, etc. Tang Gaozong once proclaimed Baekje King Fuyu once here, and Wu Zetian once proclaimed himself here, with similar functions to Jingwumen. It is also a place to receive Japanese envoys in Sui and Tang Dynasties. In 1985, the All-Japan Federation of Literary and Art Circles established a monument pavilion at Yingtianmen site, where Japanese envoys in Sui and Tang Dynasties visited Beijing.

Yingtianmen is a huge "concave"-shaped building complex, which consists of a gatehouse, a studio building, an East-West Pavilion and a cloister between them. The east-west length is 1.37 meters, and the pavilions on both sides are 36.4 meters high. Today, it is thirteen floors. There are two versions of the door, the first is "purple microscopy"; There are five worship buildings, like five phoenixes, so they are called "Five Phoenix Buildings". There are three doorways under the tower, with the imperial road in the middle, which goes in left and out right; There are three two-way exits symbolizing royal dignity in front of the gate, and twelve exits on the east and west sides, which is the highest level of the ancient gate system and the highest courtesy enjoyed by the emperor.
