Coetan Arthur is a Neolithic burial chamber lying on moorland above the cliffs of St David`s Head. It dates from about 4,000BC and consists of a huge capstone supported by a side stone. Originally, the tomb would have been covered with earth. The name translates as `Arthur`s Quoit` and, according to local legend, King Arthur played a game of quoits with the tomb`s capstone. It lies to the right of the coastal path, behind rocks, just beyond the promontory of St David`s Head when approached from Whitesands Bay.
