The site is only semicircular in plan, roughly thirty metres across from east to west, and that incomplete shape is not a sign of deterioration. The ravine's sheer drop forms the missing eastern wall, meaning whoever built this place saw no need to construct what nature had already provided.

The human-made portion of the boundary consists of a wide earthen bank, some three metres across, with a shallow external fosse, a defensive ditch, running alongside it on the outer edge. The bank stands less than a metre high internally and slightly less on the exterior, so this is not a towering fortification by any measure. That kind of modest but deliberate earthwork is typical of the enclosures found across early medieval Ireland, used variously as farmsteads, places of local assembly, or defended homesteads. What makes this one worth attention is the strategy behind its placement. The builder or builders chose a ravine edge not merely for the view or the drama of the setting, but because the natural drop eliminated the labour of constructing an entire side of the enclosure. No entrance feature is currently visible, which leaves open the question of how people moved in and out, whether that access point has simply been lost to time and vegetation, or whether it was always deliberately inconspicuous.
