What survives today is rather less tidy, and rather more interesting for it. The earthwork has shifted, over time and under pressure from field boundaries and a bordering stream, into a roughly square platform measuring approximately 29 metres north to south and 31.7 metres east to west, raised about a metre above the surrounding ground. A line of trees marks its western edge, a field wall has absorbed its southern boundary, and a fence bisects the northern side. The original circular geometry, so confidently inked on the old maps, has been slowly swallowed by the working landscape around it.

The site belongs to the category of ringfort, or rath, the enclosed farmstead type that was widespread across early medieval Ireland, typically dating from roughly the fifth to the twelfth centuries. What lifts this particular example beyond the ordinary is a feature ten metres from the western edge: a rubble-filled depression, 3.6 metres across and about 0.8 metres deep, which the Ordnance Survey cartographers labelled simply as a cave. Three lintel-like slabs are visible on its north-western side, suggesting the blocked entrance to a souterrain, an underground stone-lined passage that would originally have served the ringfort's inhabitants as a place of storage, refuge, or both. The passage appears to extend further in that north-westerly direction, though how far remains unclear. The place name itself, Inse Fhearann Na Gcléireach, carries ecclesiastical associations, the second element relating to clerics, which adds another layer of possible meaning to this quiet corner of the Iveragh Peninsula.
