It is not a dramatic monument by any measure, but its quiet precision is what makes it worth attention. The stone is flat-topped and rectangular in both plan and cross-section, measuring 1.37 metres wide, 0.25 metres thick, and standing 1.2 metres above the ground. It is orientated north to south, a deliberate alignment that hints at intention without fully disclosing it.

Standing stones are among the most common and least understood prehistoric monuments in Ireland. They were raised, most likely during the Bronze Age, for purposes that remain genuinely unclear: territorial markers, memorial stones, astronomical alignments, or something entirely outside modern categories of thinking. What survives at Kealanine is the stone itself, set into rough bogland on the western side of the Coomhola valley, in a landscape that has changed slowly enough that its immediate surroundings, rush-covered and grazed, probably resemble what they looked like when the stone was placed. That continuity of setting is itself unusual.
