Construction workers recently unearthed a well dating back more than 2,000 years in the economic and technological development zone of Qingdao in east China's Shandong Province.
Archaeologists have verified that the well was a typical Han Dynasty (206 BC - 220 AD) construction after examining potsherds, as well as patterns and designs on the blue and white tiles.
The well, the first discovery of its kind in the coastal city, was found 15 meters below ground, and is 2.3 meters in diameter and five meters in depth.
The well has a unique structure, with its upper part, 2.2 meters in depth, being built by inserting pottery pieces slantwise and the lower part by laying bricks upright.
