What looks at first like a slightly raised circular platform, perhaps thirty metres across, is in fact a rath, one of the thousands of earthen ringforts that once served as the enclosed farmsteads of early medieval Ireland. This one is univallate, meaning it has a single enclosing bank rather than the multiple rings found at more elaborate sites, and it survives well enough to read the logic of its original design.

The bank that defines the enclosure still rises to 1.4 metres on its outer face, though only about 0.6 metres above the interior, giving the site an asymmetry that is characteristic of how these structures were built. Earth was typically dug from a surrounding ditch and piled inward to form the bank, and here the exterior fosse, the defensive ditch, remains visible in two sections: from the north-east around to the east, and from the south around to the west. The fosse runs to about 1.2 metres wide and sits roughly 0.6 metres below the level of the surrounding land. Two gaps interrupt the bank, one measuring 3.6 metres to the north-east and a narrower one of 1.4 metres to the south-west. The larger of these almost certainly marks the original entrance. This description was first set down by C. Toal in the North Kerry Archaeological Survey, published in 1995, which catalogued sites across this part of the county and remains a foundational document for the area's archaeology.
