They would be notable enough simply for their setting, but the taller of the pair carries something that elevates it further: an ogham inscription, a carved circle, and a sloping groove whose purpose remains unexplained. Ogham is an early medieval Irish script in which letters are rendered as groups of notches and lines cut along the edge of a stone, typically read upward from the base. This stone bears the inscription on both edges of its south-east-facing side, making it doubly marked.

The taller stone stands 2.1 metres high and measures roughly half a metre across at its base. Its companion stands 1.33 metres away, the two aligned on a north-north-east to south-south-west axis. The scholar R. A. S. Macalister, working in 1945, read the inscription as CATVVIRR MAQI LUGUVVEC, a formula typical of early ogham stones in which MAQI means "son of", giving something close to "Catvvirr son of Luguvvec." The reading is not entirely secure: a flake of stone has spalled away just above the fourth notch of the final letter, leaving that section close to illegible. Higher up the same face, 1.6 metres from the ground, is a grooved circle roughly 16 centimetres in diameter, with a downward-sloping groove about 20 centimetres long carved beneath it. No clear parallel or explanation for this combination of marks appears to have been settled on, and it sits there quietly alongside the inscription, adding a second layer of ambiguity to a stone already doing a great deal.
