Xujiamao Site

　　The Xujiamao Site is located on the first and second terraces along the west bank of the ??shui River in Xujiamao Village, Juyuan Town, Chenggu County, covering an area of approximately 6 square kilometers. Along the east edge of the site by the ??shui River, there is an artificially built rammed earth wall, about 5 kilometers in length, with a remaining height of 0.5 to 2.8 meters and a rammed layer thickness of 0.15–0.20 meters. The specifications of the rammed pits and the width of the wall are unknown. The site contains gravel-tempered pottery, gray pottery, red pottery, rope-patterned pottery, pebbles, and artifacts such as jars, basins, pots, bricks, and tiles. To the west of the wall, the ground is scattered with large amounts of gravel-tempered red pottery, gravel-tempered gray pottery, red pottery, gray pottery, fine and coarse rope-patterned pottery, as well as bricks and tile fragments. Additionally, the site features earthen mounds of varying sizes. Cross-sections reveal a base layer of river pebbles covered by a cultural stratum, 0.1 to 1.2 meters thick. Some cross-sections show layers of lime, some of which are suspected to have been artificially rammed. Judging from the pottery shards found on the surface, the site spans a long period of time, including the Yangshao era, the Warring States, Qin, and Han dynasties, as well as the Tang and Song dynasties. The site is well-preserved and covers a broad historical range, making it of significant value for the study of Chenggu’s history.
