Panlongcheng (simplified Chinese: 盘龙城; traditional Chinese: 盤龍城; pinyin: Pánlóngchéng) or Panlong City is an archaeological site associated with the Erligang culture (c. 1500–1300 BCE)[1] during the Shang dynasty period (c. 1600–1046 BCE).

The site at Panlongcheng was sparsely inhabited during the Erlitou period (c. 1900–1500 BCE), consisting mainly of several small settlements and occupying an area of around 200,000 square metres (0.20 km2; 2,200,000 sq ft).

During the early Erligang period, the site suddenly grew rapidly, reaching an area of around 1 km2 (0.39 sq mi).

The central town was 75,000 square metres (0.075 km2; 810,000 sq ft) surrounded by a hangtu, or rammed earth, wall.

In Hubei Province, other sites such as Jingnansi and Baimiaozhu also feature Erlitou or Late Erlitou–Early Erligang type of ceramics.
