Congrats to the Mitch.mob for the FTF.

Parc Cwm long cairn 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 which was built around 5850 years ago during the early Neolithic Period. A trapezoidal cairn of rubble, the upper part of the cromlech and its earth covering have now been removed, it is about 72 feet long by 43 feet, and 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. The cromlech was discovered in 1869 by workmen digging for road stone. An excavation later that year revealed human bones now known to have belonged to at least 40 people, animal remains, and Neolithic pottery. Samples from the site show the tomb to have been in use for between 300 and 800 years.
