The structure is modest in every dimension, measuring roughly four and a half metres east to west and just under three metres north to south, yet what makes it quietly arresting is how it was built. Whoever raised these walls worked with what the hillside offered, incorporating an outcropping of natural rock and a boulder directly into the northeast to southeast section of the wall rather than clearing them away. The result is something between construction and negotiation with the landscape.

Drystone walling, built without mortar by carefully selecting and stacking stones so their weight and fit hold them in place, is among the oldest and most widespread building techniques in Ireland. Here the wall survives to a height of around 0.9 metres in places, though it has partially collapsed, and its thickness of roughly 0.55 metres suggests a reasonably sturdy original structure. The site overlooks a river valley, and its south-facing aspect would have offered both shelter and light, practical considerations that point to actual habitation or at least regular human use, though the precise period of occupation is not recorded. The bog that has since crept up around the walls has, in its way, preserved them, holding the lower courses in place even as the upper sections have begun to slip.
