Parc le Breos Burial Chamber

Parc Cwm long cairn, also known as Parc le Breos burial chamber, is a partly restored Neolithic chambered tomb, identified in 1937 as a Severn-Cotswold type of chambered long barrow. The cromlech, a megalithic burial chamber, was built around 5850 years before present, during the early Neolithic. It is about seven 1⁄2 miles west south–west of Swansea, Wales, in what is now known as Coed y Parc Cwm at Parc le Breos, on the Gower Peninsula.

A trapezoidal cairn of rubble – the upper part of the cromlech and its earth covering now removed – about 72 feet long by 43 feet, is revetted by a low dry-stone wall. A bell-shaped, south-facing forecourt, formed by the wall, leads to a central passageway lined with limestone slabs set on end. Human remains had been placed in the two pairs of stone chambers that lead from the passageway. Corpses may have been placed in nearby caves until they decomposed, when the bones were moved to the tomb.
