The Ordnance Survey's second edition map already marked it as a "site of", suggesting that by the nineteenth century its identity was uncertain even to those who mapped it. Yet this small enclosure carries a name, Cahereernark, or in Irish Cathair Uí Ruairc, placing it within the tradition of the caher, a type of stone-built ringfort common in Munster. Ringforts of this kind were typically the enclosed farmsteads of early medieval Ireland, their circular or oval banks and walls demarcating a family's living space and livestock from the surrounding landscape.

The structure survives as a subcircular bank, roughly 14.8 metres across north to south and 18.1 metres east to west, built from large boulders at its base and filled out with earth and smaller stones. The bank is not uniform in appearance: it stands only about one metre high on the interior at the north-west, but rises to nearly three metres on the exterior at the south, where the natural slope of the ground lends it an unexpectedly imposing profile. A gap of around two metres at the south-east is thought to mark the original entrance. On the western side, a large upright slab, roughly 65 centimetres tall and 1.35 metres wide, still stands on edge within the bank, and a small cairn of stones is gathered against the outer face of the bank near that same south-east gap. The field wall that now cuts through the centre of the site is a later intrusion, the kind of agricultural reuse that has quietly altered countless monuments across Kerry over the centuries.

The site is classed as a "possible" caher rather than a confirmed one, partly because the use of earth and small stones alongside the boulders blurs the line between a purely stone-built cathair and a more earthen rath. That ambiguity is itself part of what makes it worth attention: it sits in the grey area between monument types, a reminder that early medieval builders worked with what the land gave them, and that tidy modern categories do not always map cleanly onto the past.
