The monument comprises the remains of a earthen built round barrow, which probably dates to the Bronze Age (c. 2300 - 800 BC), and is located in a prominent position on the Cefn Llwyd ridge. The barrow is circular in shape on plan and has a rounded profile, measuring 15m in diameter and 1.8m high. Also present is a large white quartz stone 1.8m in length, situated c. 100m north of the barrow, which may be contemporary.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The features are an important relic of a prehistoric funerary and ritual landscape and retain significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence. Barrows may be part of a larger cluster of monuments and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive. It is two circles measuring 28m and 7m in diameter.
