The remains of a Great Wall castle dating back to the Ming Dynasty (1368-1644) were discovered in northwest China’s Shaanxi Province, said the Shaanxi Academy of Archaeology Tuesday.

Architectural relics, including two courtyards, were found at the remains of the Qingpingbao castle, located in Jingbian County, Yulin City.

The courtyard on the south side is relatively large at 60 meters long and 25 meters wide. Its walls, houses, and brick floors are well preserved.
