Coetan Arthur

Coetan Arthur dolmen, also known as Arthur's Quoit is the remains of a Neolithic burial chamber (also known as a quoit). It dates from around 3000 BC. The site, situated on the hillside close to St Davids Head in Pembrokeshire, Wales, is the collapsed chamber of what is presumed to be a passage grave which also has a round barrow. The massive capstone measures around 6 m (20 ft) by 2.5 m (8 ft 2 in) and is supported on one side by an orthostat approximately 1.5 m (4 ft 11 in) in height. The headland is in the care of the National Trust and the site is a scheduled ancient monument.
