The monument comprises the remains of a burial cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated within open moorland on an outcropping ridge above Afon Prysor. The stone built cairn is circular on plan and measures about 6m in diameter and up to 0.5m in height. Several definite kerbstones are visible. The cairn has been deliberately positioned below the summit of the ridge, on a slight terrace but set back from the leading edge. The cairn commands fine views, particularly to the S.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual. The monument is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits and environmental and structural evidence, including a buried prehistoric land surface.

The area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular and measures 25m in diameter.
