That near-perfect squareness is already unusual; most early Irish enclosures are roughly circular or oval, reflecting the ringfort tradition that dominated rural settlement across the country for much of the first millennium. Whatever its origins, this one departs quietly from the norm.

The enclosure is defined by an earthen bank that rises about a metre on both its interior and exterior faces, with stretches of stone-facing still visible in places. Beyond the bank, a fosse, the external ditch that would originally have reinforced the boundary, no longer reads as an obvious feature; it survives mainly as a slight depression of around 20 centimetres on the southern side, and elsewhere as a difference in the way vegetation grows, the kind of trace that only becomes legible once you know what you are looking for. Inside, the ground is grass-covered, with furze colonising the north-east quadrant and rushes gathering in the wetter western half near the bank. That wetness points to something else: the Ordnance Survey's six-inch map, surveyed in 1842, shows an indentation in the bank at the south-west corner that was clearly designed to accommodate a spring well. The well itself has since vanished from the surface entirely, leaving only that careful notch in the earthwork as evidence that someone, at some point, considered the water source worth preserving rather than burying.
