At a recent time, archaeologists announced that some 800-year-old city walls and gates had been unearthed in Chongqing Municipality, southwest China.
This archeological digging project was launched in February at Baidi Township - an important military fortress in history.
During the project, twenty parts of city wall, gates, defense towers and arsenals have been found. Those faraway components have been verified as dating from the Southern Song Dynasty (1127-1279) to Qing Dynasty (1644-1912). In addition, more than 300 pieces of artifacts, mainly iron weapons and some ceramic, copper and stone products have also been excavated.
According to the archaeologists, the discovery of this excavation has delineated the layout of Baidi Town. Some other unearthed cultural relics outside the town have shown a complete and consummate defense system has been established in Baidi for a long time.
