This circular enclosure, measuring roughly 20 metres across, sits directly against the southern edge of a hillfort, creating an intriguing archaeological puzzle. The enclosure’s perimeter is marked by a low, moss-covered stone bank, most clearly visible along its northeastern and eastern edges, though it becomes increasingly difficult to trace as you move towards the south and west.

The interior of the enclosure presents an interesting landscape; flat and grass-covered on the surface, yet notably stony underfoot, with expanses of natural limestone bedrock incorporated throughout. This isn’t surprising given the monument’s location on a broad seam of limestone that extends both north and south beyond the enclosure itself. The relationship between this enclosure and its neighbouring hillfort remains somewhat mysterious, as the slumped outer slope of the hillfort’s stone bank appears to overlap where the two monuments meet, obscuring their exact connection.

About 25 metres to the south, archaeologists have identified what may be a hut site, suggesting this area saw sustained human activity in the past. The entire complex sits within pastoral land, where centuries of weather and vegetation have softened the ancient stonework into gentle undulations in the landscape. Compiled by Jane O’Shaughnessy in 2015, this site represents one of many such enigmatic monuments scattered across Donegal’s limestone ridges, each holding clues to how our ancestors organised and defended their communities.
