What makes it worth pausing over is not just the bank of earth and stone that traces its outline, but what survives beneath the surface: a probable souterrain, an underground passage or chamber typically cut into the ground and lined with stone, which once served early medieval inhabitants as a place of storage, refuge, or both.

The ringfort, known in Irish as a rath, measures approximately 45.8 metres on its northwest to southeast axis and 43.5 metres northeast to southwest, making it a fairly typical example of the type that once dotted the Irish landscape in their tens of thousands during the early medieval period, roughly 500 to 1000 AD. A fosse, meaning a defensive ditch, runs around the exterior of the bank, though the eastern through southwestern arc of the enclosure has lost its visible surface traces entirely. Inside the enclosure, alongside the probable souterrain, there is also a feature recorded as a cereal-drying kiln, a corn-drying structure associated with the processing of grain harvests, suggesting this was a working agricultural settlement rather than a purely defensive site. Together, the souterrain and the kiln point to a community that farmed, stored produce, and took precautions against the uncertainties of early medieval life in the west of Ireland.
