What makes this particular rath worth attention is not just its survival but the presence of a souterrain in its interior, a subterranean passage or chamber of the kind typically associated with early medieval settlement, used variously for storage, refuge, or both. The two details together, an organised defensive enclosure and a hidden underground feature, suggest a site that was once someone's home, or at least the carefully managed centre of a household with something worth protecting.

The rath measures roughly 37 metres in diameter and is defined by two earthen banks with a fosse, or ditch, between them. A double-banked rath of this kind represents a more substantial investment of labour than a simple single-bank enclosure, and such sites are generally interpreted as belonging to people of some local standing in the early medieval period. The inner bank is still visible across much of its arc, though in places the enclosure is marked only by a scarp, a natural-looking slope that is in fact the eroded remnant of a deliberate construction. The fosse survives along the south-west to north-east stretch, and sections of the outer bank remain legible to the south-west and north-west. A trackway runs just outside the inner bank along the southern arc, and a field wall has been driven through the monument at two points, a reminder that agricultural practicality has never been especially respectful of prehistory. The gaps in the inner bank on the west and north sides are modern openings rather than original entrances. The souterrain itself lies in the west-north-west sector of the interior; souterrains are usually dry-stone lined and roofed, running underground for several metres, and they appear with some regularity inside ringforts across Ireland.

The site sits in the former demesne lands of Eyrecourt, an estate associated with the Eyre family whose house nearby was one of the more remarkable Restoration-period buildings in the west of Ireland. The earthwork, of course, predates all of that by the better part of a millennium, indifferent to the demesne that was eventually laid out around it.
