A cairn, in the Irish landscape, is typically a mound of heaped stones, sometimes marking a burial, sometimes the result of accumulated ritual over generations. This one is not visible at ground level. What survives instead is its paper trail, a feature recorded twice on Ordnance Survey maps from different centuries, and each time in a slightly different place.

The 1838 six-inch map shows the carn positioned approximately 100 metres to the south-south-west of the nearby church, noted in the south-west corner of the field that contains both church and graveyard. By the time the 25-inch map was produced in 1908, the annotation had shifted, placing the feature around 110 metres to the south-south-east of the same church. Whether this reflects genuine uncertainty about the cairn's location, some change on the ground between the two surveys, or simply inconsistency between surveyors is not clear. Writing in 1883, a scholar named Comerford found himself equally unsettled by a more fundamental question: he could not determine whether the carn had been raised over a grave or accumulated by pilgrims who came to visit the church. Both were common enough practices in early Christian Ireland, and both could leave behind a similar mound. That ambiguity was never resolved, and now the feature itself has vanished from sight entirely, leaving only two contradictory map positions and an open question about what the stones once meant.
