The surrounding bog has acted as a kind of passive guardian, discouraging the kind of agricultural disturbance that has erased so many comparable sites elsewhere in Ireland.

The enclosure is oval in plan, measuring roughly 45 metres north to south and 20 metres east to west. Along its northern arc, a substantial earthen bank survives, some 4.3 metres wide, rising about a metre above the interior and a little over a metre and a half above the exterior ground level. Elsewhere around the perimeter, the definition comes from a scarp rather than a built-up bank, where the ground simply drops away at the edge of the raised area. This combination of bank and scarp is fairly typical of early enclosures in Ireland, which were used across a long span of prehistory and the early medieval period as farmsteads, cattle enclosures, or focal points for a settled community. Without excavation it is impossible to say what period this particular example belongs to, or what went on inside it, but the choice of a limestone outcrop surrounded by bog suggests a deliberate use of natural topography, placing the enclosure on ground that was both drier and more defensible than the wetlands around it.
