They have been there long enough that nobody recorded who built them or why, and their silence on that point is part of what makes them interesting. One is corbelled, meaning its drystone walls curve inward and overlap in successive rings to form a self-supporting roof without mortar or timber, a technique used in Ireland from prehistory well into the early medieval period. The other shows no corbelling at all, its walls rising straighter and slightly taller, suggesting either a different builder, a different period, or simply a different idea about how to keep the rain out.

The two structures were recorded as part of the Corca Dhuibhne archaeological survey published by J. Cuppage in 1986, a systematic effort to document the extraordinary density of ancient remains on the Dingle Peninsula. The first hut measures 3.1 metres in diameter, stands 1.6 metres high, and has walls nearly one and a half metres thick. The second is slightly smaller in diameter, between 2.3 and 2.5 metres, but taller at 2.15 metres, with walls varying from 1.2 to 1.8 metres in thickness. Both are built from drystone, meaning the stones are laid without any binding material, relying entirely on their own weight and careful placement to hold together. Whether these were shelters for people moving livestock to summer pasture, refuges for travellers crossing the mountain, or something else entirely, the record does not say. The steep slope they occupy would have made construction effortful and habitation demanding, which suggests whoever used them had good reason to be there.
