That combination, a deliberate enclosure built not around a raised, defensible position but around a low-lying dip in the earth, is what makes this site quietly puzzling. Most enclosures of this type in Ireland occupy commanding ground; this one wraps itself around a depression, with a hillock rising to the northeast looking down on it rather than the other way around.

The enclosure is roughly subcircular, measuring about 40.6 metres north to south and 37 metres east to west. Its drystone wall, a construction technique in which stones are stacked without mortar and rely on careful placement and gravity for their integrity, runs to a maximum height of 1.6 metres and a width of 0.8 metres. The builders used random medium-sized blocks and slabs, laid horizontally, with larger stones forming the basal course. What complicates any simple reading of the site is how closely the wall resembles the ordinary field walls that abut it on the north, east, and southwest sides. It is possible to stand beside it and see nothing more than a continuation of the agricultural landscape around it. A raised rim of ground, about four metres wide, runs along the inner face of the wall on the western side, and a narrow entrance gap of 2.4 metres opens at the north-northwest, bordered on its western side by a single large boulder and oriented, curiously, towards rising ground rather than away from it. The interior is level and grassy, not raised above the surrounding terrain, the wall simply containing what the land already offered.

The site is partly tumbled in sections and heavily colonised by brambles, ivy, and hawthorn, which makes a close inspection of the full circuit difficult. The entrance boulder is perhaps the clearest single feature to orient yourself by on approach.
