It is easy to walk past without registering what it is: a drystone hut, built without mortar, its walls still standing to a height of one and a half metres. The interior diameter is just 2.8 metres, barely enough for a person to lie down in comfort. The walls vary in thickness from just over 80 centimetres to more than a metre and a quarter, which tells you something about the effort involved in raising it and the need, presumably, to keep the weather out.

Drystone huts of this type are scattered across the Dingle Peninsula and belong to a tradition of field architecture that spans many centuries, though placing any individual example in a precise period is rarely straightforward without excavation. They were used variously by farmers, herders moving livestock to summer pasture in a practice known as transhumance, and occasionally by those living more permanently on marginal upland ground. The structure at Coimín An Daingin was documented by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey, a detailed inventory of the Dingle Peninsula that remains one of the more thorough regional surveys of its kind in Ireland. The surrounding landscape, on the fringes of the Dingle hills, would have supported seasonal grazing, and a hut of this size fits that context well, though the site itself has not been dated precisely.
