Bamboo Well is located in the Imperial City of Yancheng, with a history of about 3,000 years. The well is about 7 meters deep with square wellhead. Four corners of well are fixed with logs with a diameter of 10 cm. Thin bamboo is woven around the well wall to strengthen the well wall and filter the well water.

Such unique well is called “Bamboo Well”, as one of the early water well styles in China, mostly found in southern plain. Archaeologists found a pottery pot at the bottom of the well testified to be a tool used for fetching water, which proved that humans have settled here for a long time.
