What makes it worth pausing over is its shape: a D-profile, roughly two and a half metres across at its widest east-to-west span, with one side formed not by built stonework at all but by a natural face of outcropping rock. Whoever constructed this structure looked at the hillside and decided the landscape itself could do part of the work.

The site is a hut site, a category of simple, small-scale enclosure found across upland Ireland and generally associated with seasonal or occasional occupation, perhaps by people working the higher ground during summer grazing. The builders here showed a practical intelligence in their approach to an awkward slope. Rather than levelling the ground from scratch, they raised the interior floor slightly at the southern end and cut it back into the hillside at the northern end, each adjustment modest in itself, around fifteen centimetres of raise and twenty centimetres of cut, but together enough to produce a usable, level floor. The curving stone wall that defines most of the perimeter is low and relatively thin, surviving to a height of only about twenty centimetres with a thickness of roughly forty-five centimetres, and its stones protrude above the surrounding bog surface. The straight western side, some three metres long, is that natural rock face pressed into service as a ready-made wall.
