It measures just 0.33 metres high and 0.37 metres wide, modest enough to overlook entirely, yet its western face carries a plain equal-armed cross, and its upper edge is cut with three deliberate notches. Those notches are the quietly puzzling detail. They are not decorative in any obvious sense, and no clear explanation survives for why they were made.

The stone is one of several cross-inscribed slabs associated with the remains of Teampall Bhaile Bhoithín, known in English as Ballywiheen Church, a simple rectangular structure whose ruins still stand in the same graveyard. Cross-inscribed stones of this kind are a recurring feature of early medieval Irish ecclesiastical sites; the equal-armed or Greek cross, carved without a base or any elaborate knotwork, is among the oldest and plainest forms used to mark graves or define sacred space. The site sits within the broader landscape of Corca Dhuibhne, the Dingle Peninsula, a stretch of southwest Kerry unusually dense with early Christian and prehistoric monuments. The slab was recorded and described by J. Cuppage in the 1986 Dingle Peninsula archaeological survey, a foundational document for understanding the area's layered past.
