A caher, sometimes called a cashel, is a type of early medieval stone ringfort, its perimeter defined by a substantial dry-stone wall rather than an earthen bank. The hut inside this one measured 3.8 metres in internal diameter, a modest but not unusual size for a structure of its kind, and sections of its stone facing survive from the north around to the south-east, revealing the construction method: an outer and inner skin of dressed stone enclosing a rubble core between them. The entrance is no longer visible, buried under the same collapse that has flattened much of the wall.

What makes this particular hut worth pausing over is the spread of material lying to the east of it. A band of stone collapse extends four metres outward from the external face, which gives a sense of how substantial the original structure must have been. Archaeological survey work by A. O'Sullivan and J. Sheehan, published in their 1996 survey of the Iveragh Peninsula through Cork University Press, recorded the hut as part of the wider caher complex at Killagurteen. Such internal hut sites are relatively common features within cahers across south Kerry, where early medieval farming communities built their stone enclosures as much for livestock management and household use as for defence, but the visible quality of the stonework here, even in its ruined state, suggests a building put together with some care.
