That kind of survival is unusual. Corbelled drystone construction, a technique in which flat stones are laid in overlapping courses that gradually close inward to form a self-supporting dome or roof, is ancient and demanding to execute well. That this example remains whole, rather than collapsed into the familiar ring of tumbled rubble that marks most such sites, makes it quietly remarkable.

The hut is modest in its dimensions: 2.5 metres in diameter and 1.8 metres high, which would have allowed a person to stand, just about. Its entrance faces west, a lintelled opening a little over half a metre wide and 70 centimetres tall, leading through a passage 1.1 metres long into the interior. Inside, a small recess is cut into the south-east wall, and above it what appears to be a window opening, details that suggest a degree of deliberate planning beyond simple shelter. The entrance opens westward into a small enclosure measuring roughly 3 by 2 metres. The site was recorded and described by J. Cuppage in the 1986 Dingle Peninsula archaeological survey, a comprehensive study of the Corca Dhuibhne region that catalogued the extraordinary density of early remains across this part of Kerry. The hut sits within an old field system on the ridge, which means it almost certainly formed part of a working landscape, used for seasonal grazing, farming, or perhaps the kind of transhumance, the practice of moving livestock to upland pastures in summer, that shaped so much of early Irish rural life.
