The monument comprises the remains of a burial cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated on the precipitous NW summit of Yr Eifl. The stone-built cairn is roughly circular on plan and measures about 11m in diameter. The base of the cairn is substantially intact and undisturbed and measures up to 1.5m in height. A modern cairn now crowns its summit.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The well-preserved 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 20m in diameter.
