Wanping Fortress, also known as Wanping Castle, is a Ming Dynasty fortress or "walled city" in Fengtai District, Beijing. It was erected in 1638–1640, with the purpose of defending Beijing against Li Zicheng and the peasant uprising.
From the beginning, it functioned as a military fortress. From west to east, it measures 640 meters, and from south to the north 320 meters, making it a half-square shape.
The fortress has two gates: the east gate, named Ever Prosperous Gate, then renamed as Majestic Gate, and the west gate, named Favorably Govern Gate.
