One of UNESCO's World Heritage sites, the park has a collection of dolmen (megalithic stone tombs) and other relics uncovered from 49 villages in Suncheon, Boseong, and Hwasun counties. They were excavated before the Juam lake creation in 1984, when the land was submerged. The original excavated area included Paleolithic sites with a total of 140 dolmens from nine different clusters.
