Situated on top of a low hill within the Pantmawr Rabbit Farm (site 38), is an enclosure which is quite different in character to the farm enclosures, and is probably of earlier date. It is roughly circular in shape and measures about 30m in diameter internally. It is bounded by a heavily robbed limestone boulder wall, its width varying between 1m and 3m, height varying between 0.2m and 0.7m. Limestone outcropping seems to have been incorporated in the N and W sides. There is no apparent entrance.
