Most early Irish enclosures are roughly circular, the familiar ring of an earthen bank or stone wall that once defined a farmstead or settlement. This one is semicircular, with one straight, slightly convex northern side that cuts against the slope rather than flowing with it, as if whoever built it was working with a boundary already fixed in the landscape, or perhaps against the hillside itself.

The enclosure measures roughly 20 metres north to south, with that straight northern edge running 23 metres across. It is not a single uniform structure. The northeastern to southeastern arc is formed by an earthen bank, retaining traces of external stone facing along its eastern stretch, which suggests at least some degree of deliberate construction rather than simple piled earth. A scarp, essentially a natural or cut slope used as a boundary, continues the line from southeast to southwest, and the remains of a further earthen bank carry it around to the northwest. The northern side, the anomalous straight one, is defined by a bank cut into the upslope behind it, meaning it was effectively dug into the hillside rather than built up from the ground. A small stream runs along the eastern arc. All of this is now largely buried under rush-covered grazing, and the interior of the enclosure is substantially obscured by vegetation. Without excavation, it is not possible to say with certainty what the enclosure was for, or when it was made, though earthwork enclosures of this kind in Kerry are frequently associated with early medieval settlement and agriculture.
