Yancheng Ruins, Changzhou 江苏常州春秋淹城
The Yancheng Ruins in Wujin, Changzhou, are the remains of a walled city of the Spring and Autumn period. Three rings of walls and three moats nest one inside another, making it one of the better-preserved city sites of that era in China. Today the earthen walls are thickly wooded, and a Spring and Autumn themed amusement area has been built beside the ruins.
