This ancient cashel, roughly 13 metres in diameter, consists of a scattered ring of stones that have weathered down to about 20 centimetres in height. While time has taken its toll on the structure, careful observation reveals traces of what may have been an outer defensive wall, now visible only as a subtle discolouration in the surrounding heather.

The fort's entrance arrangements remain somewhat mysterious; a two-metre gap in the northeast section might mark the original doorway, though another causeway cuts through the northwestern walls, suggesting multiple access points or later modifications. Inside the enclosure, visitors can spot the remnants of what appears to be a more recent addition: a two-metre wide circular stone foundation that likely supported a trigonometrical station, one of those surveying points once crucial for mapping Ireland's terrain.

In the southeast quadrant, a horseshoe-shaped depression catches the eye, though this may simply be a natural feature of the hilltop rather than anything constructed by human hands. Despite its ruined state, the fort's strategic position makes clear why this spot was chosen for fortification; whoever controlled this height controlled the sight lines for miles around, making it an ideal defensive position in ancient Donegal.
