The monument comprises the remains of a small round cairn, which probably dates to the Bronze Age (c. 2300 - 800 BC). It is located on the top of Cefn Merthyr Cynog ridge, with good views to the S. The cairn is sub-circular in shape on plan and measures 7m in diameter and 0.6m in height. Although there has been some superficial disturbance on the surface, the majority of the cairn appears to remain intact.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual practices. The monument 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 structural and environmental evidence, together with intact burial or ritual deposits.

The scheduled area comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular in shape on plan and measures 20m in diameter.
