The structure is modest in scale, measuring about ten metres east to west and eight and a half metres north to south, with walls around a metre thick and standing close to a metre high where they survive. What makes it quietly remarkable is the care taken in its construction relative to the hillside itself: the interior has been deliberately levelled, raised by about sixty centimetres on the southern side and cut a full metre into the slope on the northern side, so that whoever used it had an even floor despite the gradient of the hill.

This kind of enclosure, a walled area set within a broader field system, would likely have served as a stock enclosure or a small domestic compound, possibly associated with seasonal or permanent habitation in the uplands. The presence of a hut site within the enclosure's southern quadrant, and a second hut site roughly nineteen metres to the south-south-east, suggests this was not an isolated structure but part of a small cluster of occupation. The rubble scattered across the interior and along the perimeter is typical of collapse over time, the upper courses of the wall having gradually slipped inward and outward. The whole sits within a wider field system on the rough hill grazing above the Blackwater River valley, with Kenmare Bay visible in the distance to the south. That long view, across boggy upland to an estuary, frames the kind of marginal landscape where communities historically pushed agriculture and settlement as far as the terrain would allow.
