These ramparts were found at an expressway construction site by experts with the Jiangxi provincial archaeological research institute.

According to the experts, the ramparts are made from earth, and measure 15 meters wide and cover an area of more than 40,000 square meters.

Research on earthenware pieces unearthed from the ramparts showed that the walls were built in the Shang Dynasty(1600 B.C.-1100 B.C.) and the Zhou Dynasty(1046 B.C.- 256 B.C.).

The discovery will provide valuable clues on the study of culture and history of ancient tribes and towns in the area, the experts said, adding that further excavation on the ramparts is going on. Enditem
