What makes it quietly arresting is the engineering still legible in the ground: two substantial earth and stone banks enclosing a roughly circular area approximately 44 metres across, separated by a wide, deep fosse. A fosse, in this context, is simply a ditch, dug to make the inner enclosure harder to approach. There is also a slighter external fosse, though this is now only clearly traceable on the northern side. The whole thing amounts to a serious piece of defensive or status-marking architecture, the kind of enclosure that in early medieval Ireland would typically have belonged to a farming family of some local standing.

The entrance survives with unusual clarity at the north-north-east. A gap four metres wide in the inner bank leads onto a causeway, just under seven metres across and rising about 45 centimetres above the surrounding fosse floor, before a second gap through the outer bank completes the passage. Elsewhere the site has fared less well: the inner bank is almost completely levelled along the south and south-west, where later agricultural activity has left its mark. Vague traces of cultivation ridges running north to south are still visible across the interior, suggesting the enclosed space was at some point turned over to tillage rather than left as a farmstead yard. A stream forming the old townland boundary with Clanhugh Demesne cuts through the south-east of the site, and the remains of two separate field boundaries intersect the monument from the west and south-west, each representing a different era of land management quietly overwriting an older one. Cambridge University's aerial photography programme captured the outline of the monument clearly in 1968, at a time when cropmarks and earthworks across Ireland were being systematically recorded from the air for the first time. Kilpatrick Well lies just 165 metres to the south-west, suggesting this corner of Westmeath was a place of some local significance long before and possibly long after the ringfort was built.
