It is a fionnán enclosure, a category that takes its name from the Irish word for a particular coarse grass, Molinia caerulea, which tends to colonise and mark out these low, often circular earthworks in upland and boggy terrain. The vegetation itself becomes a kind of indicator, outlining a human-made boundary that might otherwise be invisible to a passing eye.

The reclassification draws on the work of O'Sullivan and Sheehan, whose 1992 study of the Iveragh Peninsula helped researchers better understand these grass-ringed enclosures as a distinct type within the broader landscape of Kerry's early field monuments. The site had previously been recorded in both the Sites and Monuments Record of 1990 and the Record of Monuments and Places of 1997 simply as an enclosure, a catch-all term that covers everything from prehistoric ringforts to medieval farmsteads. The fionnán designation narrows that considerably, pointing toward a particular kind of upland enclosure that survives not through dramatic earthworks but through the subtle persistence of vegetation growing along boundaries that people shaped, possibly centuries or millennia ago.
