The monument comprises the remains of a large burial cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated within enclosed moorland, in a slight hollow on the rounded summit of Bryn Du ridge. The stone-built cairn is circular on plan and measures about 13m in diameter and up to 0.5m in height. Several possible kerb stones are visible on the N side.

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 to be 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.
