It is not large; the interior diameter is just 2.8 metres, the walls rise to 1.8 metres, and those walls are between 0.9 and 1.5 metres thick. What it lacks in scale it compensates for in construction technique. Corbelling is a method of building a domed or vaulted roof by laying successive rings of dry unmortared stone, each course projecting slightly inward over the one below until the gap closes at the top. No cement, no keystone, just weight and geometry holding everything together. Structures built this way on the Dingle Peninsula have survived for centuries, some for considerably longer.

The site was recorded in J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne area, the Dingle Peninsula, a study that catalogued the remarkable density of early remains across that landscape. The hut sits about 50 metres upslope from a neighbouring monument, suggesting it was not an isolated oddity but part of a wider pattern of activity on the mountain. Who used it, and when, is not recorded. Structures of this type on the peninsula range in date and function, sometimes associated with early Christian monasticism, sometimes with secular settlement or seasonal farming activity, and often difficult to date precisely without excavation. The rocky terrain around Ballysitteragh would have made it a demanding place to live or work, which raises the question of what drew people up there in the first place.
