They are not ruined in the conventional sense, the way a castle or church falls apart above eye level. Instead, these boundaries have subsided into shallow peat, leaving only low, discontinuous ridges that protrude just thirty centimetres or so above the surface, ghostly traces of a landscape that was once carefully divided and managed.

The network covers a roughly rectangular area of around two hundred metres along its longer axis and sixty metres across, oriented northeast to southwest along a natural terrace in the rough pasture. The walls themselves, where they survive, are about sixty centimetres thick. What makes the site particularly interesting is the variety of their alignment: some stretches run in straight lines, others curve, suggesting the boundaries were laid out to accommodate the particular shape of the terrain or the needs of whoever was farming here. Peat formation has buried much of the system over time, which is partly what preserves it. Peat accumulates slowly and organically, sealing what lies beneath rather than scattering it, so the walls remain legible even in collapse. The site is recorded in the Archaeological Inventory of County Cork, which documents it among the many relict field systems that survive across the county's upland and marginal ground.

The walls themselves offer few obvious clues about their age. Relict field systems of this kind in the Irish uplands can range from the early medieval period back to the Bronze Age, and without excavation or dating evidence the Dunlough example cannot be placed more precisely. What the remains do make clear is that this slope, now rough pasture at the margins of productive land, was once subdivided with some intention, by people who moved stone, measured ground, and worked this awkward, ridge-backed terrain.
