The monument comprises the remains of a stone circle, which probably date to the Bronze Age (c. 2300 - 800 BC). The site is located on a slight E-W running spur within open moorland above the River Wye. The circle is 18m in diameter and consists of 24 stones, of which only 9 are now visible protruding above the ground surface. The presence of a further two stones, now missing, can be estimated by the spacing between some stones. The visible stones protrude no more than 0.6m above the ground surface. On the E side of the circle are two slabs set at right angles to the others, with a low slab between them, suggesting a portal entrance on this side.

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. Stone circles are often 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.
