This is a rectangular double ditched enclosure located north-east of Forden Gaer Roman settlement (NPRN 94012). The site is known from air photograph mapping (Crew 1980, 740) and trenching (Blockley 1990, 22-4). The enclosure is about 70m north-east to south-west by 65m. Trenching, in 1987, showed that both ditches were V-profile. Roman pottery was recovered from the upper fill of one ditch. The enclosure lies upon a gentle rise about 75m south of a less regular cropmark enclosure (NPRN 309200). Fainter cropmark features hint at an outer enclosure, about 100m deep, on the south-west side. This is cut by a Roman road.

The enclosure is most likely to be a Romano-British temple enclosure, or temenos, and as such can be paralleled to other known or suspected Roman temples in eastern Wales, at Plasnewydd (NPRN 309755) and Gwehelog, Llancayo Farm, Usk (405805).
