Roughly D-shaped, it measures about 28 metres from north to south and 11 metres from east to west, its edges defined by a scarp, essentially a deliberate change in ground level, that drops between half a metre and one and a half metres depending on where you stand. The straight side faces west, into the hill, while the curved portion faces outward. Grass and disturbed soil now cover the whole thing, softening what were once presumably more pronounced edges.

Enclosures of this kind, platforms cut or built into sloping ground and bounded by a scarp or bank, appear throughout Ireland and tend to be associated with early medieval settlement, though dating any individual example without excavation is difficult. What can be said about this one is its position: it sits on a knoll partway down a steep east-facing slope, with the headwaters of the Owenbeg River lying around 150 metres to the east. That proximity to a reliable water source, combined with the slightly elevated, sheltered position on the knoll, suggests whoever chose the site was thinking practically. The Owenbeg flows roughly north to south through this part of Leitrim, and a location just above its upper reaches would have offered both water access and a degree of natural drainage on the slope above.
