The wall, roughly 45 metres long and standing about 0.8 metres high, is built from large upright slabs set flush against one another, a construction style quite different from the loose-stacked dry-stone walls most people associate with the Irish countryside. It runs south-east from the roadside, bends east, then turns north-east for a final stretch of around 12 metres before ending at a river. That it survives at all is largely down to the bog, which, while gradually swallowing the wall, has also preserved it from the kind of robbing and disturbance that cleared so many ancient field systems elsewhere.

The wall sits just south of a medieval road that once connected Kenmare with Castletownbere, a route crossing some of the more demanding terrain in south-west Kerry. The road gives the field boundary a useful reference point in time, though the wall itself may be considerably older. It is classified as a relict field system, meaning it belongs to an agricultural landscape that was abandoned long ago and never reintegrated into later farming patterns. Further stretches of comparable walling survive nearby, both to the south of the road and to the north-west on its other side, suggesting that what remains visible is a fragment of something once much more extensive. About 70 metres to the west lies a five-stone circle, a type of small monument particularly associated with south-west Ireland, where five stones are arranged with one laid flat at the centre. The proximity of the circle to the field system raises quiet questions about who was farming this hillside and when, though the notes do not press a firm answer.
