The carving is a sheela-na-gig, a category of medieval stone figure found across Ireland and Britain, typically depicting a female form with exaggerated or exposed genitalia. Their purpose remains debated: theories range from fertility symbols to apotropaic carvings designed to ward off evil, and they appear most often embedded in church walls or castle stonework, which tells something about how the medieval mind wove the sacred and the unsettling together.

This particular figure was removed from Aghadoe Castle during its demolition and passed into the keeping of the owners of nearby Aghadoe House, where it remains in private possession. The carving shows a female figure in raised relief, projecting roughly a centimetre from the stone face. The head is large and triangular, with eyes, nose, mouth, and ears all clearly worked. The torso is defined by a visible rib-cage and small pendant breasts. The legs are splayed in the characteristic sheela-na-gig pose. One detail sets this figure slightly apart from many others in the tradition: the left hand is raised and appears to be holding something, though whatever object it once grasped has broken away. The right arm hangs at the figure's side, fingers still legible on the hand. Both feet are damaged, the right broken off entirely and the left partially lost. The figure is catalogued as number seven in Cherry's 1992 survey of Irish sheela-na-gigs.

Because the slab is held privately at Aghadoe House, it is not accessible as a public site. Its existence is, however, documented, and the survival of the carving after the castle's demolition is itself a reminder of how these figures tend to outlast the structures they once decorated.
