The Wanghai Tower is located on the west of Fenghuang Mountain in the southern suburb of Zhaotong City. It was built in 1760, the 25th year of the reign of Emperor Qianlong of the Qing dynasty, by Shen Shenglin, the magistrate of En’an County. During the end of the Guangxu period (1871-1908), the local gentleman Yang Luheng further built in front of the building additional chambers, corridors, and walls. He also constructed pavilions on the east and west bridges, and planted flowers and trees in the surroundings. Now the Wanghai Tower and the Wanghai Park have become a sought-after place for recreation and education.
