What survives today is a roughly circular enclosure about 24 metres across, its boundary formed by a flat-topped earthen bank that still stands over a metre high on its outer face. The builders clearly understood the slope they were working with: the interior has been deliberately raised by about 65 centimetres above the surrounding ground level to create a level platform, a practical solution to a hillside site that also gives the enclosure an almost stage-like quality when viewed from below.

This is a rath, the Irish term for a ringfort, the most common type of early medieval monument in Ireland. Ringforts were typically farmsteads enclosed by one or more earthen banks and ditches, providing security for a family and their livestock. Here, a shallow external fosse, a ditch running just under 20 centimetres deep and about 1.9 metres wide, is still traceable along the south-eastern arc of the enclosure, hinting at the original defensive perimeter. On the inner face of the bank, between the north-west and north-east sections, stone facing remains visible, suggesting the earthwork was reinforced with masonry at some point, a detail that gives the construction a more deliberate, considered character than a simple mounded bank might imply. The northern portion of the interior has since been overtaken by overgrowth, softening the geometry that the original builders worked to impose on the land. What makes the site particularly layered is that the rath also served, at some point in its history, as the location of Kilnarovanagh Church, a now-separate recorded monument occupying the same ground. The pattern of a church planted within or beside an earlier secular enclosure is well attested in early Irish ecclesiastical history, and finding both traditions compressed into a single 24-metre circle gives this quiet Kerry field an unusual density of meaning.
