It is recorded as a cross-base, the type of socketed stone block that would once have anchored a standing cross in place, but the attribution comes with a caveat: it might just as easily be a fragment of an unfinished millwheel. The circular socket cut into its surface could support either reading, and nobody has settled the question.

What makes the object quietly interesting is precisely that ambiguity. Granite cross-bases of early medieval or medieval date are not uncommon in Ireland, typically serving as the footing for high crosses or processional crosses in ecclesiastical enclosures. The circular socket is the key feature, designed to receive the tenon at the base of a cross shaft. But millwheels, particularly those left incomplete at the quarry or workshop, can produce strikingly similar forms, and without further diagnostic detail the two interpretations remain equally plausible. The stone is described as crude, suggesting it was never finished to a high standard, which arguably strengthens the millwheel theory as much as it weakens it.
