What makes it quietly unusual is not simply its age but its setting: the fort sits on a high natural ravine, with the ground falling sharply away to the south-southwest, meaning the builders were working with the landscape rather than against it, using the natural topography to amplify whatever defensive or social purpose the enclosure served.

The site is a broad oval, roughly 55 metres along its northwest-southeast axis and 28 metres across, demarcated by a scarped bank, that is, a bank formed by cutting into and shaping the natural slope rather than simply piling up material. That bank measures around 7 metres wide and 2.2 metres high, dimensions that suggest a structure of some substance. A castellated entrance, meaning a formal gap or passageway built through the bank rather than a simple break, faces the east-northeast. Inside, at the northwest end of the interior, lies a souterrain, an underground stone-lined passage or chamber of the kind commonly associated with early Irish ringforts and thought to have served for storage, refuge, or both. The site was noted in an 1896 publication, and the record as it stands was compiled by Geraldine Stout and uploaded to the national monuments database in August 2011.

The townland straddles the Lucan and Pettycanon area of County Dublin, and the ravine setting means the approach on foot involves some unevenness underfoot. The surviving earthworks, particularly the scarped bank, are most legible when vegetation is low, so late autumn or winter visits tend to reward closer inspection. The souterrain is a separate recorded feature within the interior and should not be disturbed or entered. As with most earthwork sites in agricultural or semi-urban fringes, the perimeter is best read by walking the full circuit of the bank rather than approaching from a single direction.
