It is compact almost to the point of severity: 3.4 metres across, 2 metres high, with walls more than a metre thick. The entrance, lintelled and just 85 centimetres wide, is the kind you stoop to pass through. Inside, there may once have been a wall niche, a shallow recess built into the stonework, perhaps for a lamp or a few small objects.

The structure is corbelled, meaning the walls were built by laying successive courses of flat stones, each one angled slightly inward and overlapping the one below, until the courses met at the top without the need for mortar or a keystone. It is one of the oldest building techniques found on the Dingle Peninsula, and examples survive here in greater concentration than almost anywhere else in Ireland. This particular hut sits in Baile an Lochaigh in County Kerry, a townland on the Corca Dhuibhne peninsula, and was recorded in J. Cuppage's 1986 archaeological survey of the area. The survey catalogued an extraordinary density of early remains across this stretch of west Kerry, and this hut, catalogued as number 1054, is one of the quieter entries, noted without drama and without a date.
