A city where history is at home
China DailyArchaeologists have unearthed the ancient city of Changgan, which has pushed back the recorded history of Nanjing, capital of Jiangsu province, by 600 years. The city, now capital of East China's Jiangsu province, was once widely considered to have an urban history of 2,500 years, but new archaeological research rewrites that. Dating to the Shang and Zhou dynasties, archaeologists found that the "city's walls were flanked by trenches", which is an important indicator of a fortification system used by ancient cities, says Chen Dahai, head of the archaeological excavation team, and an associate professor at the Nanjing Archaeological Research Institute. Aside from portions of the city's walls and trenches, archaeologists discovered a fascinating history of a city with water wells built in the late Shang Dynasty, kilns for brick firing and a pit for pig sacrifices.
