That it survives at all is something of an accident. The stone, measuring just over a metre in length and nearly as wide, now sits among a collection of field clearance stones along a boundary wall on a steep south-south-east-facing slope at Baile An Ghlaisín in County Kerry, at around 168 metres above sea level. It was almost certainly moved there at some point, its original context lost when farmers dragged it to the field margin alongside other large rocks cleared from the land.

The mark itself is a cupmark, the most common form of prehistoric rock art found in Ireland, made by grinding or pecking a rounded hollow into a rock surface. They appear across the country from at least the Neolithic period onward, though their precise purpose remains genuinely unknown; theories range from ritual or astronomical significance to boundary marking or simple symbolic communication. This particular example is modest even by those standards, a single cupmark on a smooth, rectangular sandstone slab, fractured but otherwise well-preserved. It does not sit in isolation entirely: another rock art site lies roughly 45 metres to the east, suggesting the broader landscape here once held more deliberate significance than the present field boundaries might imply.

The stone rests on the western side of a north-south field boundary, somewhere in rough hill pasture with open views across the valley to the east, south, and west, with Dingle Bay visible in the distance to the south. Whether that orientation was ever meaningful to whoever made the mark is impossible to say, but the placement, even in its displaced state, gives the site an unexpectedly contemplative quality.
