SHIJIAZHUANG, Nov. 4 -- A tomb dating back 830 years to the Jin Dynasty (1115-1234) has been found in northern China, local authorities said Monday.

The tomb was discovered on the site of a natural gas pipeline project in Liulin Village, Xingtai County of Hebei Province, according to the county's institute of cultural relics and archaeology.

The round-shaped tomb is 1.9 meters tall, 1.9 meters wide and 1.7 meters long with tile frescoes on the vault.

Archaeologists were able to tell the age of the tomb from the inscribed dateline and believe that it belonged to a local gentleman or landlord.

"The tomb will provide valuable materials for research on the local funeral institution, burial custom and social conventions at that time," said Hua Penghui, head of the institute.

Two other tombs were also found nearby and are under excavation.
