Beneath and around them, the collapsed remains of a drystone wall trace the outline of a structure barely two metres across, its subcircular shape just legible if you know what you are looking for. The wall, once perhaps the full enclosure of a small hut, has sunk to a height of roughly thirty centimetres, its stones spread to a width of about half a metre. It is the kind of thing that reads as nothing at all to a passing eye, and as something quietly significant once you pause over it.

Drystone construction of this kind, built without mortar, was used across Ireland for millennia, from prehistoric shelters through to the seasonal huts associated with transhumance, the practice of moving livestock to upland grazing in summer. Crohane sits in precisely the landscape where such temporary or semi-permanent occupation would have made sense, on the rocky break of a slope where a herder or a small farming family might have sheltered for a season. The hut's modest dimensions, less than two metres in either direction, suggest a functional rather than a residential purpose. What makes the site stranger still is that a second hut site lies approximately five metres to the north, the two structures close enough to suggest they were used together, though whether simultaneously or across different periods is not recorded.
