An ancient nine-sided well, bearing a wooden structure, with a history of over 2,000 years was discovered in North China's Shanxi province, archaeologists announced Tuesday.
The well, located 570 meters from the ancient city ruins in today's Yangquan city, was first seen during shantytown renovation in November 2019, according to the provincial institute of cultural relics and archaeology.
The well is 9 meters deep and 4.5 meters wide at the mouth, archaeologists said. Timberwork dating analysis showed that the well was built and was in use from the late Warring States Period (475-221 BC) to the early Western Han Dynasty (202 BC-AD 25).
