The Gochang Dolmen Site (8.38 ha) features the largest and most diversified group, and is centered in the village of Maesan, along the southern foot of a group of hills running east/west. Over 440 dolmens of various types have been recorded in this location. - in: http://whc.unesco.org/en/list/977/
