Most ringforts consist of a single bank and ditch, but this one presents a double defensive arrangement, with two earthen banks separated by a fosse, and the remains of a further outer fosse beyond that. The overall diameter runs to 34 metres, and the enclosure has enough surviving structure to give a clear sense of how substantial and deliberately engineered the original construction was.

A fosse, in this context, is simply a ditch, typically dug to provide material for the bank thrown up beside it and to present an obstacle to anyone approaching. Here the intervening fosse between the two banks is flat-bottomed and approximately three metres wide, and it remains waterlogged along its north-to-south stretch, which may well have been a deliberate feature of the original design rather than simple drainage failure. The inner bank stands nearly two metres above the exterior ground level, and the outer bank, though partially lost, survives well along the northern arc. A causeway entrance at the south-west cuts through both banks, with the outer bank retaining stone facing on its north-west side; that facing continues for a short distance along the bank's internal face, a detail suggesting the entrance was both reinforced and finished with some care. The north-east arc has been clipped by a road boundary over time, and part of the outer bank to the north-west has been absorbed into the surrounding field boundary system, the fate of countless such monuments across Ireland as agricultural land was reorganised over the centuries.
