Guangwu Fortress, Military fortress in Shanyin County, China

Guangwu Fortress is a walled town in Jiuguangwu Village, Zhangjiazhuang Township, Shanyin County, about 5 km from Yanmen Pass. Its walls form a rectangle 338 m east-west and 498 m north-south, with a perimeter of 1,654.94 m, standing 8 m high and 3.4 m thick at the top. The brick-clad walls have 12 bastions, four watchtowers and gate towers on the east, south and west sides.

Guangwu Fortress was first built in 917, the first year of the Qianheng era of the Liao dynasty, and was rebuilt during the Hongwu and Wanli reigns of the Ming dynasty. In 2006 it was listed in the sixth batch of Major Historical and Cultural Sites Protected at the National Level.

The fortress stands beside Jiu Guangwu village in Zhangjiazhuang township, Shanyin County, about 5 km from Yanmen Pass. The name Guangwu is shared by the walled village itself, whose residents live within and around the Ming-era brick-faced ramparts. The site is listed as a Major Historical and Cultural Site Protected at the National Level, and the village keeps its layout tied to the old gates and wall lines.

The walled town lies about 5 km from Yanmen Pass in Jiuguangwu Village, Zhangjiazhuang Township, Shanyin County. The walls stand 8 m high with a 3.4 m top, and the circuit measures 1,654.94 m, so allow time to walk the full perimeter. Three gate towers face east, south and west; the south gate is the usual way in.

The walls began as rammed earth and were only faced with brick during the Ming reconstruction, so the brick skin visible today is later than the Liao foundation of 917. Twelve rectangular bastions (mamian) project from the 8 m-high circuit, and four watchtowers once stood on it.
