It is classified as a univallate ringfort, meaning it was defended by a single enclosing bank or wall, and it measures about 23.5 metres across internally. What makes it worth pausing over is the nature of that enclosure: the surrounding bank, rising to 2.4 metres on its outer face, appears to have been built not from earth but from stone, and is now a long, grass-grown ridge of collapse. Straight field fences have taken over much of the western and southern arc, absorbing the monument into the ordinary geometry of the farmed landscape.

The site has been recorded under the name Garfinny Cathair, a detail noted by a researcher identified as Curran. The word cathair in an Irish archaeological context typically refers to a stone-walled enclosure, often a ringfort constructed primarily in dry-stone rather than earthen ramparts, and the surviving evidence here supports that reading. Inside the enclosure, two circular hut-sites are arranged in an east-west line across the centre. The western hut has an internal diameter of about 4 metres, with an entrance facing south-east; the eastern hut, slightly smaller at 3.5 metres across, faces west. A straight stony bank connects the northern sides of their two entrances. Between them, low banks on the southern side hint at a third structure or a roughly D-shaped courtyard area, though the collapse of material has made the full original plan difficult to read. Short sections of original wall-face survive in both huts, standing in places to just under a metre in height. The survey from which much of this detail is drawn was compiled by J. Cuppage and published in 1986 as part of the Corca Dhuibhne archaeological survey of the Dingle Peninsula.
