It is, by any measure, a small thing: a sub-circular hut whose outer walls span less than five metres east to west and just over four metres north to south. The interior is smaller still, roughly the floor space of a large garden shed. Yet the careful geometry of those low, tumbled footings, no more than thirty centimetres high in places, marks out a space where someone once chose to shelter, work, or live, overlooking a tributary of the Roughty River on the boundary between the townlands of Coolnagoppoge and Knockanruddig.

The site came to light during pre-development survey work carried out by John Cronin and Associates ahead of a wind farm project by ESB Wind Development Ltd in the area. That kind of survey, conducted under archaeological licence, is one of the main ways that previously unrecorded sites enter the historical register in Ireland, particularly in upland and marginal landscapes that have seen little formal investigation. The hut's rubble stone wall footing, between 0.7 and 0.8 metres wide, is consistent with a tradition of dry-stone construction found across Kerry's uplands, though without excavation or dating evidence it is not possible to say with confidence when the structure was built or how it was used. Sub-circular hut sites of this type can range widely in date and function, from early medieval seasonal shelters associated with transhumance grazing to much later shepherds' bothies.
