The structure is corbelled, meaning its walls curve inward course by course until the stones meet overhead without any mortar, a technique with deep roots in early medieval Ireland. It stands just over two metres tall, with walls between 1.75 and 2 metres thick, and an internal diameter of five metres. What makes it genuinely puzzling are two small square passages, roughly 35 centimetres across, that tunnel horizontally through the wall thickness at the north and west. Nobody has settled on a convincing explanation for what they were for.

The original lintelled entrance, on the east-south-east side, is only 0.7 metres high, low enough that anyone entering would have had to crouch or crawl. This kind of deliberately restricted opening is sometimes associated with early ecclesiastical or monastic enclosures, and here the doorway leads not directly into the hut interior but into an irregularly shaped enclosure attached to the structure. A second, larger gap on the north-east side is modern and was not part of the original design. The site sits within the broader archaeological landscape of Corca Dhuibhne, a part of Kerry unusually dense with early Christian remains, clochán settlements, and ogham stones, and was recorded as part of J. Cuppage's systematic survey of the Dingle Peninsula published in 1986.
