Roughly twenty-five to thirty metres across, the enclosure is defined not by standing walls but by a scarp, a steep cut or drop in the ground, that rises from around one metre at its southern edge to two metres at the north, with a flat berm running along its base. These earthwork enclosures are among the more enigmatic monument types in the Irish landscape; they may have served as settlement sites, ceremonial spaces, or stock enclosures, and without excavation it is rarely possible to say which. What the shape of the ground itself communicates is that someone, at some point, went to considerable effort to define this circle and separate it deliberately from the hillside around it.

The site sits on an east-facing slope of a ridge that runs roughly northwest to southeast along the foothills of the Blackstairs Mountains, a granite range that forms part of the border between Wexford and Carlow. About two hundred and fifty metres to the east, the Urrin River runs on a north-south course through the valley below. The positioning is characteristic of enclosures across Ireland, elevated enough to command a view of the surrounding terrain and close enough to a water source to be practical. The southern portion of the enclosure has been partly cut away by a later east-west field bank, the kind of incremental agricultural reshaping that has quietly erased or damaged countless monuments across the country over centuries.
