That overlap, between a prehistoric boundary and an administrative one drawn centuries later, hints at how persistently these old lines can organise a landscape.

The enclosure is roughly oval, measuring approximately 66 metres across its north-east to south-west axis, and is defined by a well-preserved earthen bank that runs from west through north to east and around to the south-west. Where the bank has survived intact, a small block of stone laid on edge at the south-west side may indicate internal revetment, meaning the bank was once reinforced with stonework on its inner face to keep the earth from slumping. A gap of about 1.6 metres on the south-east side is interpreted as a possible original entrance. The interior is not flat; it slopes gently downward from south-east to north-west, and a large water hole sits just outside the south-eastern edge near the presumed entrance. What this enclosure was actually for remains open. It is not a ringfort in the standard sense, though a ringfort does sit 190 metres to the south-east, suggesting this part of the ridge was a focus of activity over a long period. Enclosures of this kind could have served as livestock compounds, ceremonial spaces, or settlement boundaries, and the distinction between those categories was not always sharp in early medieval Ireland.

The site sits on the north-western side of a ridge summit that commands views to the north-west, north-east, and south-west, which may say something about why it was placed here. That kind of visibility was rarely accidental.
