It measures roughly ten and a half to eleven metres across, and its edges are defined not by any obvious wall but by a scarp, a subtle step in the earth, with stones that protrude here and there or press upward underfoot. The western arc of this scarp is the most legible, reaching about 0.7 metres in height at its north-west end, and carries a faint internal lip that hints at a collapsed enclosing wall. Two breaks in the circuit, one to the north-east and another to the south-south-east, might be original entrances, or might simply be gaps worn into already fragmentary remains. What makes the site quietly puzzling is how little can be said with confidence about it. Its date is unknown. Its function is unknown. It is not shown on the Ordnance Survey six-inch maps of either 1838 or 1919, which means it either went unrecorded by the surveyors or had already been absorbed so thoroughly into the agricultural landscape that it was indistinguishable from it.

The surrounding field deepens the ambiguity rather than resolving it. Immediately to the north-east of the circular feature sits a loose cairn of field clearance stones, the kind of pile that accumulates over generations as farmers remove surface stones to make ground workable. Three metres to the east, a relict field wall, a boundary that has long since fallen out of use, runs roughly north to south as a row of large contiguous stones. And across the field as a whole, cultivation ridges are visible in multiple orientations, the kind of corrugated earthworks left by spade or plough tillage, probably from the post-medieval period. Some of the stones incorporated into the scarp at the south-east may themselves be field clearance material, suggesting that whatever the original structure was, it has been added to, disturbed, or simply confused by centuries of agricultural activity. The possibility also exists that the circular outline owes something to underlying bedrock, that the land itself is doing some of the shaping. The enclosure sits on a natural rise with long views south-west and north-west across low-lying pastureland, the Atlantic visible in the far distance on both bearings, a position that might once have meant something, or might be coincidental.
