The structure measures just 2.3 metres in diameter, its wall surviving to around half a metre in height, with some of the slabs set at right angles to the perimeter rather than running parallel to it. That detail, minor as it sounds, hints at deliberate construction rather than accidental accumulation, the work of someone who understood how to lock stones together against the pull of a hillside.

The interior has been levelled by whoever built it, slightly raised at the southern end and cut into the slope by about 20 centimetres at the northern side, a practical arrangement that would have kept a packed-earth floor reasonably flat on ground that naturally tilts away. A narrow entrance, just 0.6 metres wide, faces the south-east, a common orientation in prehistoric and early medieval Ireland that combined shelter from prevailing westerly weather with the benefit of morning light. A second hut site of the same general type sits roughly 70 metres to the south-west, suggesting this was not a solitary outpost but part of a small cluster of activity on the mountain. Structures like these are broadly described as hut sites, a deliberately cautious term that acknowledges we often cannot say with certainty whether a given example was a permanent dwelling, a seasonal shelter for those tending animals on the uplands, or something else entirely. The boggy, rough-grazing context here is consistent with the kind of marginal land that was used for summer pasturing, a practice with deep roots in Irish rural life.
