It is not a particularly tall stone by Irish standards, but its position gives it an outsized presence: the hilltop offers open views in every direction, the kind of unobstructed horizon that suggests the location was chosen with some care, whether for ceremony, boundary-marking, or something else entirely that has long since passed out of memory.

The stone measures 1.51 metres by 0.65 metres at its base, giving it a broad, slab-like profile rather than the tapering finger shape seen at many other sites. What sets it apart from most prehistoric standing stones is a detail on its southern face: a bench mark, the cut symbol used by ordnance surveyors to record a point of known elevation, typically a broad arrow beneath a horizontal notch. Ordnance surveyors working across Ireland from the nineteenth century onwards would occasionally use convenient upright stones as reference points, effectively borrowing prehistoric infrastructure for modern cartographic purposes. The Clodagh stone carries this layering quietly, a prehistoric monument pressed into bureaucratic service and then left to settle back into the bog.
