The enclosure measures roughly 28 metres northeast to southwest and 22 metres northwest to southeast, and it is ringed not by one bank and ditch but by three concentric earth and stone banks, each separated by its own fosse. That degree of elaboration, a triple-ramparted rath, was unusual even in early medieval Ireland, when ringforts were the standard form of enclosed farmstead for a farming and pastoral society. A causewayed entrance gap on the northeast side, where the banks were left open and bridged by a raised approach, would have controlled movement in and out with some deliberateness.

The site sits on an east-facing slope of steeply rising ground in pasture, with Bishops Lough lying roughly 440 metres to the north-northeast. Two further ringforts sit within a few hundred metres, one to the northeast and one to the southwest, suggesting this part of Froghanstown was a settled and organised landscape rather than an isolated farmstead in open country. Inside the enclosure, a sub-rectangular hut site occupies the centre of the interior, while a second hut site sits in an annexe on the northeast side of the fort, an additional enclosed area attached to the main ringfort. The townland boundary with Ranahinch cuts across the monument from the northwest, meaning a line drawn for administrative purposes in a much later century now bisects something considerably older.
