Carreg Coetan Arthur Burial Chamber is a Neolithic chambered tomb or dolmen, dating to around 3000 BC. This small chambered tomb from the New Stone Age is one of the best-preserved of a number of burial sites clustered along the slopes of the Nevern Valley. A large (4m) wedge-shaped capstone balances on two of its four original stone uprights. It would once have been covered in earth.
Excavations of the site have uncovered artefacts including Neolithic pottery, stone tools and cremated human bones.
The ‘coetan’ part of its name is a reference to the game of quoits, often associated with monument of this type. According to legend, King Arthur himself played the game with the stone of this tomb.
