Buan Guam-ri Dolmens, designated as Historical Site No. 103, is comprised of southern-style dolmens. Dolmen refers to a particular structure of a tomb created during the Bronze Age. Dolmen is largely classified into two groups – Southern-type that has small footstones supporting large top stone; and Northern-type which is shaped like a desk. In Guam-ri, there were originally 13 dolmens, but only 10 remain. Most of the dolmens have 8 small footstones propping up one large top stone, compared to the dolmens in other regions which normally have 4 footstones.
