Roughly circular, with a diameter of around 37 metres, it survives now only as a scarp, a low earthen slope or edge that traces the ground from the northern side around through east to south. The western half is gone, removed by quarrying at some point in the past. What remains is dense, overgrown, and easy to miss entirely.

Enclosures of this kind are among the most common yet least understood monuments in the Irish landscape. They may have served as ringforts, the enclosed farmsteads that were built and occupied across Ireland from the early medieval period onwards, though without excavation it is impossible to say with certainty what function any individual example served. The setting here is geologically interesting in its own right. Glacial ridges, sometimes called eskers, are long narrow mounds of gravel and sand deposited by meltwater rivers flowing beneath ice sheets during the last glacial period. Whoever chose this spot selected the very end of one such feature, a position that would have offered both drainage and a degree of natural elevation above the surrounding grassland.
