Yet those low, tumbled walls once formed a corbelled hut, a structure built without mortar by stacking flat stones so that each course projects slightly inward over the one below, eventually closing to a roof. The technique is ancient and demands considerable skill; the fact that this one has fallen inward rather than outward is itself a kind of evidence, suggesting the corbelled dome simply gave way over time rather than being deliberately dismantled.

The structure is modest in every measurable sense. It spans just 1.4 metres east to west and 1.7 metres north to south at its widest, with walls 0.8 metres thick and standing no more than 0.6 metres at their highest surviving point. A possible entrance, roughly 0.4 metres wide, opens to the west. All of it is formed from large limestone flags, now collapsed inward into a rough interior scatter. It sits approximately 20 metres to the west of a neighbouring recorded site. These dimensions and details come from F. Coyne's 2006 upland archaeological study, published under the title 'Islands in the Clouds', which surveyed the archaeology of Mount Brandon and the Paps, both significant Kerry upland landscapes with long histories of human activity ranging from early Christian pilgrimage routes to prehistoric settlement. That study placed this small ruin within a broader pattern of upland use, where temporary or seasonal shelters of this kind would have served those working or travelling through the mountains.
