简介：The circumference of Laiyuan Fort is more than two miles. The city wall is three feet and five feet high. It is based on a strip of stone and has a tower built at each corner. The fort has three gates in the south, north and west, and faces Qingshui River in the east. It builds embankments and dams on the riverside, and sets up water fences in the river. Its defensive capabilities are no less than that of Zhangjiakou Fort.
