The foundations of walls built of tamped earth dating back over 1,800 years have been discovered in Hezhou City, in south China's Guangxi Zhuang Autonomous Region.
Archaeologists say that the wall, belonging to the Eastern Han Dynasty (25-220 A.D.), was originally 23 to 30 m in width and more than 650 m in length.
The walls surrounded Linhe Town, one of four major towns of the Han Dynasty in Guangxi.
Of the four towns, only Linhe Town is well preserved, with stone-flagged streets, ancient houses, wells, temples and government offices.
