BEIJING: A series of tombs built thousands of years ago, some filled with ancient treasures, have been discovered by archaeologists at a construction site in China's central Henan Province.
The archaeological site in Zhoukou City's county-level Xiangcheng city, consists of 21 tombs built thousands of years ago, spanning from Warring States Period (475-221 BC) and East Han Dynasty (25-220), said Han Yanzhen, a scholar at cultural heritage institute of Zhoukou City.
Among them, 19 tombs are earth pit in shape and another two are brick-chambered tombs. Archaeologists said all but five tombs were damaged by robbers.
Lots of funeral paraphernalia including pottery, bronze wares and jewelry were found in the tombs, state-run Xinhua news agency reported on Sunday.
A well-preserved bronze sword was one of the rarer discoveries, said Han, adding that that it was well preserved due to the local soil conditions.
Archaeologists said the treasures in the tombs can help researchers to better study the shape and structure of tombs, culture and customs between Warring States Period and East Han Dynasty.
