At roughly 28 metres across, it is a modest example of an early medieval ringfort, the circular or near-circular enclosed farmsteads that were built and occupied in Ireland broadly between the fifth and twelfth centuries. What gives this one a particular edge of interest is the presence of a possible souterrain in its interior, an underground passage or chamber, typically stone-lined, that might have served for storage, refuge, or both. Rabbit burrows have disturbed the central ground, which adds a layer of ambiguity to what lies beneath.

The earthwork itself survives in partial form. An arc of earth and stone bank, about 2.6 metres wide and standing to just under a metre in height, runs from the east around to the south-southwest; elsewhere the boundary reads as a scarp, where the hillock edge simply drops away rather than carrying a built-up bank. The interior tilts gently downward from the centre toward both the south and north. What makes the cartographic record here quietly interesting is a small discrepancy between two nineteenth-century Ordnance Survey maps. The 1846 six-inch map shows the enclosure as circular, at around 25 metres in diameter, while the 1894 edition records it as slightly oval, open at the northeast, suggesting either that surveyors read the surviving earthwork differently across the intervening decades, or that the site's condition had changed in the interim.
