In this regard, Dr. Cha Man Dal, head of an excavating party under the Archaeological Institute of the academy, told KCNA:

The group tombs are located on a hill, about 2 kilometers northeast of Chondok-ri seat, Pongsan County of North Hwanghae Province.

There are nearly 30 tombs in four rows in an area of 185 square meters with individual ones around it, which shows the area was a big burial site with hundreds tombs.

Most of tombs are 10 meters in diameter and 2 meters in height and the biggest one is 17 meters in diameter and 2.4 meters in height. The tombs are arranged at intervals of 10-20 meters and can be divided into the earthen one with a stone chamber and the other with two stone chambers, all of them with arch-style or inclined-plane ceilings before getting collapsed.

Unearthed from the tombs were human and horse bones, bronze spoons and decorations, silver-clad iron nails, iron handles of coffin, grey earthenware and other remains.

The newly-unearthed tombs and remains will serve as material evidence to give fresh understanding of advanced cultural development of Koguryo, a powerful state that existed in the East for a thousand years, and precious treasures showing the good qualities of the Korean nation.
