A rath is a ringfort, the kind of enclosed farmstead built across Ireland from roughly the early medieval period, and it is not unusual to find structures inside one. What is unusual here is that this inner feature has its own concentric arrangement of bank, ditch, and outer bank, a miniature defensive or demarcating logic nested within the larger one.

The enclosure is slightly raised above the surrounding ground, its earth-and-stone bank measuring around 0.6 metres wide, with an internal height of only about 0.1 metres but an external face rising to 0.5 metres, suggesting the ground level inside is elevated rather than built up. A fosse, that is a shallow ditch, runs around the external foot of that bank, approximately 0.55 metres wide, and beyond it sits a second low bank of earth and stone. The fosse is best preserved along the north-east to north-west arc of the site. The inner bank is missing along the north-west to north-east stretch, where a scarp, an abrupt change in ground level, takes its place. The original entrance, if there was a formal one, has left no trace that can now be read. The dimensions are recorded as 3.8 metres west-north-west to east-south-east, and 3.9 metres east-north-east to west-south-west, making the plan very nearly square, which is itself a relatively uncommon shape for an Irish earthwork of this kind.
