The one at Ballinderry Castle in County Galway has no interest in being overlooked. It occupies the keystone of the arch over the castle doorway, the structural and visual centre of the entrance, so that anyone passing through would have done so directly beneath it.

The carving itself is unusually detailed. The face is large relative to the body, with ovoid eyes, a wedge-shaped nose, a slit mouth, and prominent ears. What sets this figure apart from many of its type is the hair, which extends from either side of the head across the top of the stone in two distinct braided styles: a classic plait on the left and a more intricate interlace pattern on the right. The arms curve around the body, small breasts tucked beneath them, and both hands are positioned below the navel in the characteristic sheela-na-gig pose. The legs are spread wide, and the feet, though damaged, follow the same open stance. Flanking the figure are decorative motifs that are unusually varied for this type of carving: a marigold and a knotwork design on the left, and on the right a rose, a bird, and a circle with a triskele-like pattern. This combination of symbolic imagery alongside a sheela-na-gig is notable, and the figure is referenced in scholarly literature as far back as Nolan in 1901, with further discussion by Costello in 1936 and Freitag in 2004. A three-dimensional digital model of the carving has been produced by Digital Heritage Age and is accessible via the Sketchfab platform, which allows close study of the surface detail without requiring a visit to the site.
