That absence is itself curious. Most ancient or medieval stone buildings in Kerry have been recorded and plotted with some care, yet this one slipped through, either because it was deemed too recent to warrant inclusion or because nobody was looking in quite the right direction at the right time.

The structure is oval in plan and corbelled, meaning its walls are built by laying courses of stone with each course projecting slightly inward over the one below, gradually closing the space until a roof is achieved without the use of mortar or timber. Here, the final closure at the top is made with a series of flat flagstones. The interior measures roughly 2.5 metres by 1.7 metres, with a standing height of 1.65 metres, which puts it at the upper limit of what a single person could comfortably occupy upright. It has been built directly into a north-south running field wall, suggesting that whoever constructed it was working economically, using the existing boundary as one side of the shelter. J. Cuppage's 1986 archaeological survey of the Dingle Peninsula recorded the structure and noted that it may be of fairly recent construction, which in archaeological terms could still mean anything from the nineteenth century back a few generations further. The old village of Glanfahan above it hints at a landscape that has seen long and layered habitation, and small corbelled shelters of this kind were used across the peninsula for storage, as animal shelters, or as temporary refuge for those working distant fields.
