It measures roughly four and a half metres across and stands just under two metres high, built in the corbelled drystone technique, a method in which each course of stones is laid so that it projects slightly inward over the one below, allowing a roof to be closed without mortar or timber. The result is a self-supporting dome of dry-stacked rock, a form of construction with deep roots in the Irish landscape, found at sites ranging from early Christian hermitages to the famous beehive cells of the Dingle Peninsula.

The structure was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a landmark regional study that catalogued the extraordinary density of archaeological remains in this part of west Kerry. Whether the hut dates to an early medieval period of monastic or pastoral use, or belongs to a later tradition of seasonal mountain sheltering, is not firmly established. What places it in an interesting category is the word "possible" in its description: the surviving fabric is enough to suggest deliberate corbelled construction, but not so unambiguous as to settle the question definitively. Numerous sheep-folds scattered nearby suggest the area has long served as upland grazing ground, and the hut may well have sheltered a herder rather than a hermit, or both at different times.
