Tucked into a hillside in the townland of Coolnagoppoge, near Kilgarvan in County Kerry, a small rectangular enclosure was built around and against it, using the rock's bulk as a ready-made northern wall. Two low drystone walls, the kind of construction where stones are laid without mortar, run along the western and southern sides, while a single large stone slab closes off most of the eastern edge. The gap left between that slab and the southern wall is thought to mark the entrance. The whole structure measures just two metres east to west and 1.9 metres north to south, barely large enough to shelter a person or two from the wind coming off the Kerry hills.

The site had gone entirely unrecorded until 2016, when archaeologists from John Cronin and Associates were surveying the area ahead of a proposed wind farm development by ESB Wind Development Ltd. in Coolnagoppoge. Working under excavation licence 16E0127, the team identified the feature south of an existing farm track and south of the planned new access road. The wall remnants survive to only 0.20 to 0.30 metres in height and around 0.40 metres in width, little more than ankle-height courses of stone, which goes some way towards explaining why the structure had never been formally noticed before. The boulder itself rises to 0.80 metres within the internal space, extending further back into the hillside on its north side. Whether the structure served as a seasonal shelter for a herdsman, a temporary work camp, or something else entirely, the notes do not say, and the archaeology does not yet resolve the question. Its very smallness, and the pragmatic way its builders incorporated the natural landscape into the design, is quietly telling about how people once moved through and used these upland spaces.
