A wayside cairn once stood here, close to a church in Kilcahill, and according to local memory it took the form of an eight-sided flagstone roughly three metres in diameter. That is an unusual thing: not a rough heap of stones in the roadside tradition, but a shaped, octagonal slab, the kind of object that suggests deliberate craftsmanship and some degree of veneration. It was removed during road-widening works, and no visible trace remains.

The monument had a documented life across successive editions of the Ordnance Survey maps, each one recording it slightly differently, as though cartographers were unsure what to make of it. The OS Fair Plan marked the site as a small rectangular roadside recess and gave it two names: the plain label 'Monument' and the Irish designation 'Cahill na can Dherg', written in Gothic script in the manner reserved for antiquities. The first edition of the six-inch OS map simplified this to a single circular dot and the word 'Monument' in Roman script. By the third edition, published in 1933, the name had shifted again to 'Leacht Chill Chathail', a phrase that roughly translates as the memorial or gravestone of Kilcahill, though by that point no precise location was even indicated. A leacht, in Irish tradition, is a commemorative cairn or stone marker, often associated with a holy person or a site of local devotion, sometimes placed at a crossroads or boundary where passers-by might pause and pray. The progressive renaming across the maps, moving from an anglicised obscurity toward a more descriptive Irish form, hints at a community still holding some knowledge of what the stone meant, even as it was becoming harder to place on paper.

The site sits approximately 210 metres north-east of a church, which suggests it once occupied a meaningful position in the local landscape, close enough to a place of worship to carry religious or commemorative weight, yet planted at a public junction where travellers would encounter it. That relationship between church, road, and marker is now visible only in the cartographic record.
