Nearly every one of the twelve stones that once formed this prehistoric circle was broken by blasting, leaving a scatter of split quartz boulders across the hillside rather than the upright ring that once stood here. A stone circle is exactly what the name suggests, a roughly circular arrangement of standing stones thought to date to the Bronze Age, and this one, sitting on an east-west ridge with the ground falling away sharply to the south, would have been a considerable structure. Writing in 1934, Liam Price recorded a diameter of about 120 feet, close to 36.5 metres, which places it among the larger examples of its type.

The blasting that destroyed most of the uprights has left the archaeology in an ambiguous state. The scattered quartz boulders to the north-east may be the remains of a displaced revetment, the facing stones of an earthwork or enclosure wall, though this is uncertain. One of those fragments carries a curved groove on its flat upper surface, narrow and shallow, whose purpose or origin is not recorded. A single large stone survives to the south-west. The monument sits beside an enclosure, and the relationship between the two features adds another layer of complexity to a site that, even in better condition, would resist easy interpretation. The circle appears to have been noticed and described before the blasting took place, but by the time systematic survey work began, the damage was already long done.
