It measures roughly 28 metres across, which places it in the general range of a ringfort, the type of enclosed farmstead that tens of thousands of farming families across early medieval Ireland built and occupied. A ringfort typically consists of a raised bank, sometimes reinforced with stone, surrounding a circular interior where a dwelling and outbuildings would have stood. Here, a bank and fosse, meaning a ditch cut to throw up the bank material, curve around from the south-west through north to north-east, but the south-eastern arc has disappeared entirely from the surface.

The condition of the monument tells a quiet story of gradual neglect. A field wall cuts across it at both the north-east and south-west, suggesting that at some point after the enclosure fell out of use, the land was reorganised for agricultural purposes with no particular regard for what lay beneath or around it. Several breaches in the surviving bank appear to be of modern origin rather than ancient collapse, and a hollow sits in the western half of the interior, possibly the trace of a collapsed feature or simply the result of disturbance over centuries. The association with the former demesne of Hampstead House adds a layer of historical overlap: a much older piece of human activity on the landscape, predating the demesne era by many centuries, quietly absorbed into the margins of a later estate boundary.
