The monument comprises the remains of a round barrow, which probably dates to the Bronze Age (c. 2300 - 800 BC). It is located on a low summit towards the SW end of a ridge and overlooks the Afon Duad valley to the SE. The grass-covered mound is circular in shape on plan and measures 22m in diameter. It is rounded in profile and measures 1.5m in height. A N-S aligned hedgebank runs over the mound. The E edge of the barrow has been slightly cut into by ploughing.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The feature is an important relic of a prehistoric funerary and ritual landscape and retains significant archaeological potential. There is a strong probability of the presence of both intact ritual and burial deposits, together with environmental and structural evidence, including a buried prehistoric land surface. The importance of the monument is further enhanced by the group value it shares with adjacent barrows to the NE.

The area scheduled comprises the remains described and an area around within which related evidence may be expected to survive. It is circular and measures 32m in diameter.
