Only one of the pair survives, and even that survivor is a modest thing: just 1.25 metres high, with walls nearly one and a half metres thick, and an internal diameter somewhere between 4.4 and 5.3 metres. What makes it quietly interesting is that the interior is divided by a line of upright slabs, suggesting the space was organised into distinct areas rather than simply used as a single undifferentiated shelter.

Corbelled drystone construction, the technique used here, involves laying stones in gradually inward-leaning courses so that each ring slightly overhangs the one below, eventually closing to form a self-supporting roof without mortar or timber. It is an ancient method, and examples survive across the western Irish coastline in varying states of repair. This particular structure was recorded and described by J. Cuppage in the 1986 Corca Dhuibhne archaeological survey of the Dingle Peninsula, a detailed catalogue of the remarkable concentration of early monuments across that landscape. The fact that the OS maps noted a pair where only one now stands is a small reminder of how much has quietly vanished from a peninsula that still holds more than most.
