The Gochang, Hwasun and Ganghwa Dolmen sites contain the highest density and greatest variety of dolmens in Korea, and indeed of any country. Dolmens are megalithic funerary monuments, which figured prominently in Neolithic and Bronze Age cultures across the world during the 2nd and 1st millennia BCE. Usually consisting of two or more undressed stone slabs supporting a huge capstone, it is generally accepted that they were simply burial chambers, erected over the bodies or bones of deceased worthies.
