Rather than relying solely on a built-up earthen bank, whoever constructed this enclosure used the natural outcrop beneath them as raw material, cutting a fosse, essentially a defensive ditch, directly into the bedrock. The result is a structure that sits on a natural hillock in County Limerick's pastureland as though it half-grew there, the boundary between human effort and geology deliberately blurred.

Ringforts, also known as cashels when their enclosing walls are of stone rather than earth, were the most common form of rural settlement in early medieval Ireland, typically housing a farming family and their livestock within a defended perimeter. This particular example measures roughly 17 metres north to south and 18 metres east to west, and its defining bank, now worn down to an uneven scarped edge, still reaches 2.75 metres in height and spans around 8 metres in width. A revetment of stones faces the scarp from the south-west around to the north, where the vertical face of the rock outcrop itself takes over the structural role. The external fosse varies considerably as it follows the circuit: best preserved between north-west and north-east, shallower further round, and at some points entirely absent, where the rock presumably made digging impractical or unnecessary. The site was compiled by Denis Power and recorded as part of the wider archaeological survey of the region, with notes uploaded in November 2013. It is also thought to be associated with a surrounding field system recorded separately in the county's monuments register.

The interior is level and covered in rough grazing, and an Ordnance Survey trig point sits on the edge of the scarp at the north-north-west, which gives a useful locating marker when approaching across open farmland. The site is on private agricultural land, so any visit would require landowner permission. Walking the perimeter is the most instructive approach, since the variation in the fosse is only apparent once you begin to trace its full circuit, noting where the builders relied on the cut rock, where they built up stone, and where the natural topography made formal defences unnecessary.
