The Gongchen Tower (Chinese: 拱辰楼; pinyin: Gǒngchén Lóu) was a 14th-century wooden tower built on top of the northern gate of the city wall of Nanzhao, the old town and seat of Weishan Yi and Hui Autonomous County in the Chinese province of Yunnan.
The Gongchen Tower was built in 1390, the 23rd year of the Hongwu reign during the Ming dynasty, on top of the northern gate of the Weishan (then called Menghua) city wall.
It was considered a symbol of Weishan, and was listed as a key cultural protection site by the Dali Bai Autonomous Prefecture in 1988.
[3][5] A horizontal board was hung on the southern side of the tower, inscribed with the calligraphy of Kang Qin (康勤), Prefect of Menghua Prefecture during the Qing dynasty, written in 1771.
The northern side of the tower had a board inscribed with the calligraphy of Huang Dahe (黄大鹤), another Prefect of Menghua, dated 1785.
