This ancient defensive site occupies an almost circular piece of land that juts out from the coast, connected to the mainland by a narrow, low lying strip of earth. The natural geography made it an ideal defensive position; the ground rises sharply on the landward side, whilst the sea provided protection on the other approaches.

The narrow causeway that links this promontory to the mainland still shows evidence of the fort's defensive arrangements. Two sections of low stone walls run perpendicular to the isthmus, likely positioned to control access to the fortified area beyond. At the entrance to the interior, further wall sections remain visible, though centuries of weathering and collapse have made it challenging to determine whether these were part of the original defensive walls or the foundations of internal buildings that once stood within the fort.

In the northeastern part of the site, more substantial remains can be found. Here, the foundations of a stone structure measuring approximately 18.5 metres from north to south and 10.2 metres from east to west are still visible. This building would have been one of the larger structures within the fort, possibly serving as a dwelling for the site's inhabitants or perhaps fulfilling some communal function. The fort represents just one of many such coastal defences documented in the Archaeological Survey of County Donegal, which catalogued field antiquities spanning from the Mesolithic period through to the 17th century.
