Information from the Pembrokeshire Coast National Park Authority:
Cerrig y Gof (the name means “blacksmith’s stones”) is thought to date from around 3500 BC. The five box-like stone chambers stand on a low, circular mound about 15m across. This is the remains of the original cairn. Each grave has between two and six side-stones, and four of the five capstones are still present, though dislodged from their original position.
Cerrig y Gof is on private property. Public access is permitted but please be sure to close the field gate.
