Recent archaeological excavations at the site of the ancient Stone City of Houchongzhai, located in Qingshuihe County in the Inner Mongolia Autonomous Region of China, have revealed significant new details about its sophisticated three-level defensive system.

Dating between 4300 and 4500 BC, during the historical period known as Early Longshan, the city of Houchongzhai was occupied by a prosperous Stone Age civilization. With an area of 138 hectares, it is the largest and best-fortified city discovered from that period in all of Inner Mongolia.

The massive stone walls, forming an elliptical perimeter of approximately 1200 by 1150 meters, were the main findings of the initial excavations in the 1990s.
