Most ringforts, the enclosed farmsteads of early medieval Ireland, measure somewhere between 20 and 60 metres across; an enclosure approaching a quarter of a kilometre in diameter belongs to a different category of monument entirely, one whose original purpose remains harder to pin down.

The full circuit of the enclosure is not easy to read on the ground. A defining bank is visible to the north and north-north-east, and aerial imagery from the 2010s shows the curve continuing through scrub from that direction round towards the east, and possibly from the east-south-east as far as the south-west. From the south-west to the north-west, the line disappears into scrub and becomes harder to trace. A short additional stretch of bank, around 25 metres long, is visible at the north-west, and notably the road curving from north-west to north appears to follow the enclosure's line rather than cut across it, a small detail that suggests the boundary was respected long after whatever activity it once contained had ceased. Inside, the southern half holds at least three smaller enclosures clustered just south of centre, along with other internal subdivisions, giving the impression of a complex, layered use of the space over time. A cairn, a mound of stacked stones that in Irish contexts is often associated with burial or ritual, sits just outside the main bank at the north-west.
