It stands just over a metre tall and measures roughly one and a half metres in length and seventy centimetres in width, which puts it at the more modest end of the prehistoric monolith tradition. What gives it quiet interest is its orientation: the stone is aligned along an east-north-east to west-south-west axis, a detail that sounds technical but carries real weight. Many standing stones across Ireland share deliberate alignments of this kind, and while their precise purpose remains debated, solar, lunar, and funerary explanations have all been proposed by archaeologists over the decades.

Standing stones, sometimes called galláin in Irish, are among the most enigmatic monuments in the Irish landscape. They were erected across a broad span of prehistory, most commonly during the Bronze Age, and their functions almost certainly varied. Some appear to mark boundaries or routeways; others may have served as focus points for ritual activity; a few are associated with early Christian or later medieval use, repurposed long after their original meaning had faded. The stone at Lissagriffin sits on a south-east-facing slope, which suggests its position was chosen with some care, whether for visibility, for its relationship to the surrounding terrain, or for reasons that can no longer be recovered. Its proximity to Kilmoe church is the kind of layering that turns up repeatedly across Ireland, where early Christian sites were established near older prehistoric monuments, sometimes absorbing their local significance, sometimes simply sharing a landscape that had already been considered meaningful for a very long time.
