Tombs of 1,800 years ago found in Beijing

Chinese archaeologists have discovered over 290 tombs, some of which date back 1,800 years, in Yanqing County, in the northern outskirts of Beijing.

Most of the tombs were built in the Han Dynasty (206 BC-220 AD)or Tang Dynasty (618-907),. Others are believed to belong to the Jin (317-581), Yuan (1271-1368), Ming (1368-1644) and Qing dynasties (1644-1911).

All the tombs, covering an area of 44,000 square meters, had underground chambers built of brick but the shape of their ceilings were unique to their dynasties.
