It measures just over a metre in height and roughly a metre across its longest face, oriented east to west along its length. Modest by any standard, it is precisely the kind of monument that gets walked past without a second thought, which is part of what makes it worth pausing over.

Standing stones of this kind are among the most enigmatic survivals in the Irish landscape. They were erected, in most cases, during the Bronze Age, though the purposes attributed to them range from territorial markers and astronomical alignments to burial indicators and assembly points. No single explanation covers them all. The Liskillea example sits on a south-facing slope that looks down over a stream valley, a positioning that recurs often enough with standing stones to suggest it was deliberate, though what meaning that orientation carried for the people who raised it remains open. The east-west alignment of the stone's long axis adds another layer of quiet ambiguity, east and west being directions long associated with the movement of the sun and, in many cultures, with ideas about life and death. Whether any of that applied here is beyond knowing.
