Whether it fell centuries ago or was deliberately lowered at some point, nobody can say for certain, but its sheer scale makes it hard to overlook even in its recumbent state. The stone measures roughly 2.77 metres in length and just 0.3 metres in width, giving it a narrow, blade-like profile that would have been striking when upright, cutting the skyline at around two metres high.

Standing stones, as a category of monument, were erected across Ireland during the Bronze Age and possibly earlier, though their precise purposes remain debated. Some may have marked boundaries, trackways, or burial sites; others appear to have astronomical alignments. This particular stone is subrectangular in plan, meaning its cross-section is roughly rectangular rather than tapered or irregular, and its long axis runs northeast to southwest, an orientation shared by a number of other standing stones across the country, though what significance that alignment held for the people who placed it here is unknown. Its location beside the Rylane River suggests it may have occupied a meaningful position in the prehistoric landscape, perhaps marking a river crossing or a boundary in what was then a very different kind of countryside.
