Fanchengdui (archaeological site)

Fanchengdui is an archaeological site located in Zhangshu city in the province of Jiangxi, China. It is located upstream on the secondary tributary of the Gan River. The Fanchengdui site is located about 23 km east of another archaeological site, Shinianshan. The river Meng flows through the south part of the Shinianshan site roughly from northwest to southeast, before entering a primary tributary of Gan, Yuanshui. Near Fanchengdui the two rivers and Xiaojiang meet, and together they enter Gan river.

Underneath the site there is a salt mine.

The site was discovered in 1975. Three consecutive excavations were done in 1977, 1978 and 1980. The site is a mound, 1~3 meters in height relative to the surrounding plain, 124 meters in length from north to south, 100 meters from east to west - an area of over 10 000 square meters.[3]

In 2006 it was designated as the sixth protected national cultural heritage site.
