Elevated view of the cairn in the middle distance, from its side, with deciduous trees in leaf to its rear. To its front passes a wide asphalt path, dissecting flat ground of short grass. The tumulus' trapezium shape is evident, its boulders retained by a short wall, missing at the very front, left, where the rubble has tumbled out.

Parc Cwm long cairn (Welsh: carn hir Parc Cwm), also known as Parc le Breos burial chamber (siambr gladdu Parc le Breos), 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 (BP), during the early Neolithic. It is about seven ⁄₂ miles (12 km) west south–west of Swansea, Wales, in what is now known as Coed y Parc Cwm at Parc le Breos, on the Gower Peninsula.
