That is a considerable grave, and local tradition has long had an explanation for it: the person underneath was a giant.

The slab, known in the area as McCriosain's Grave, sits immediately south of a large enclosure whose origins have not been fully established. The name McCriosain is the detail that lingers. It attaches the site to a specific, named individual in local memory rather than leaving it as an anonymous curiosity, which is itself unusual. Giant-grave traditions are not uncommon across Ireland; they tend to cluster around oversized monuments or unusually large slabs, and they often serve as a folk explanation for the sheer physical scale of something that does not fit the expected dimensions of ordinary burial. A rectangular slab of this size, lying flat and unadorned in a field, invites exactly that kind of reasoning.

The grave is close to the enclosure to its north, and the two features together suggest a landscape that was meaningful to people over a long period, even if the precise relationship between them is unclear. Whether McCriosain was remembered as a local figure, a mythological one, or something in between is not recorded, but the name has stuck to the stone long enough to make it into the formal archaeological record, which is its own kind of persistence.
