In Tullycommon, County Clare, a ruined herdsman's house occupies exactly this uncertain position: recorded on all editions of the Ordnance Survey six-inch maps, it has nonetheless managed to shift, at least on paper, by roughly three hundred metres.

The trouble began when a local contributor, Tom Coffey, annotated a six-inch map to identify the ruins of a herdsman's house at a specific grid location. When that spot was physically inspected in 1999, no remains could be found. The story did not end there, however. Aerial photography from between 2012 and 2018 revealed a ruined structure about three hundred metres to the north-north-east, and it seems plausible that this is the building Coffey had in mind, the coordinates simply being slightly off. The structure itself was a modest three-roomed house with small extensions, the kind of dwelling typical of a working herdsman employed to tend livestock on larger landholdings in the eighteenth or nineteenth century. Its repeated appearance across successive OS map editions suggests it was a recognised feature of the landscape for generations, even as the people who once lived in it receded from memory.
