The Characteristics of Dolmens in the Midwest －Focusing on the Large Table-type Dolmens in the Northwest Korea and Ganghwa regions－

Large table-type dolmens in Ganghwa, Gochang, and Hwasun regions exhibit distinct characteristics that reflect shared cultural practices with Northwest Korea. These dolmens, defined by covering stones measuring over 450 cm in length and 25 tons in weight, often feature geometric ratios and turtle-shaped covers symbolizing longevity, particularly concentrated along the Han River. Unlike clustered distributions in other regions, Ganghwa's dolmens are predominantly solitary, perched on low-lying ridges or hillslopes between Mt. Goryeosan and Mt. Bongchonsan. Structural innovations, such as counterbalance tilting for stability and varied construction techniques using mortise joints, highlight advanced megalithic engineering. Archaeological findings, including bronze artifacts and pottery like spindle-shaped ceramics, suggest cultural continuity with Northwest Korea while revealing local adaptations. These insights expand the understanding of dolmen culture's regional scope, temporal phases, and symbolic significance.
