Ganghwa Dolmen Site

Prehistoric stones standing in open fields, older than the last of Egypt's pyramids.

Ganghwa Island sits where the Han River meets the sea, and hundreds of dolmens raised some three thousand years ago are scattered across its fields. The most famous — Bugeun-ri — carries a capstone of roughly 50 tonnes on two uprights, forming a giant table on empty grass. No crowds, no cramped railings: just wind off the fields and the feeling of standing in front of something that was here before every Korean dynasty. The peninsula holds the densest concentration of dolmens on earth, and Ganghwa is the doorway to understanding that.
