Okdae Dolmen

Okdae Dolmen is a megalithic tomb group in Okdae-ri, Uisin-myeon, Jindo-gun, Jeollanam-do, South Korea. The site consists of 21 dolmens arranged in an oval on a hill beside the village, approached along Donji-ri. It was investigated by a surface survey carried out by Mokpo National University Museum in 1987.

The lower parts of the dolmens have been buried or damaged, so their original construction cannot be confirmed. The group mixes medium-sized and small dolmens of uneven scale. The largest is 330cm long, 220cm wide and 70cm thick; across the group, lengths range from 110~330cm, widths from 70~280cm and thicknesses from 30~140cm.

The site is dated typologically to 700 BCE to 300 BCE, within the Bronze Age. Its tombs were built from stones scattered around the hill, whose lower parts are thought to have been destroyed. One polished stone arrowhead was recovered near the dolmens. Polished stone swords found nearby are held by the Jindo-gun Local History Museum.

Dolmens of this kind in South Korea are generally associated with the Bronze Age and early Iron Age, particularly the Mumun pottery period. They are commonly known as goindol, meaning “propped stone.” Such monuments are especially dense in the west coast area and river basins such as the Han and Nakdong, where many examples remain across the Korean Peninsula.
