From the outside, it reads as a raised circular mound sitting on a gently south-facing slope in ordinary County Sligo pasture, easy enough to walk past without a second thought. But step up to the earthen bank and look inward, and the inner face reveals something more deliberate: a vertical revetment of large limestone blocks, laid up to three courses high, each stone averaging roughly half a metre in length. That combination of an earthen outer form with a stone-faced interior is the defining characteristic of a cashel, a type of early medieval enclosure in which the structural stonework is integral rather than decorative.

The enclosure itself is roughly circular, measuring 26 metres east to west and 23 metres north to south, with the bank reaching nearly five metres in width and over a metre in internal height. Unusually, there is no fosse, the external ditch that typically accompanies a ringfort of this kind, visible at ground level. Whether one was never dug or has simply been filled and levelled over the centuries is unclear. What survives is clear enough, though: the limestone blocks, averaging around 0.5 metres by 0.3 metres by 0.2 metres, were carefully selected and set to hold the bank face vertically rather than allowing it to slump. A gap of just under four metres in the south-eastern section of the bank marks where the original entrance once stood, oriented to catch the morning light and, practically speaking, away from the prevailing westerly weather.
