The monument comprises the remains of a circular earthwork, which probably dates to the Bronze Age (c. 2300 - 800 BC). It stands on a prominent saddle in the hills with a wide panorama to the south and north-west, alongside Sarn Helen, the preserved line of the Roman road. It consists of an inner mound of c.14m diameter, standing up to 1.4m high, the central area of which is dished, lying c. 0.3m below its rim, except in the centre where an area has been dug away and later fires built, and on the southern side where a massive boulder c.3.6m long resting on its long side lies in a deep hollow. The inner mound is surrounded by a ditch c.1m wide and c.0.5m deep with traces of a slight counterscarp bank outside it. Opposite the boulder the ditch is discontinuous for a distance of c.3.5m, giving the impression of a causeway which has five smaller boulders on its western side. The origin of the site seems to be as prehistoric funerary monument consisting of features of a round barrow and recumbent stone circle. The large boulder may have originally been upright. It has also been suggested that the site was re-used as a Roman signal station.

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. Such sites 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.
