At Lios An Gharráin in County Galway, what was once reported as a potential ancient structure was found, on closer inspection, to be something considerably more modest: a short stretch of old field boundary, nine granite boulders arranged in a north to south line, running about seven metres in length and rising no more than sixty centimetres from the ground.

The site sits in flat pastureland broken by outcrops of bare rock, the kind of landscape common across much of Connacht where thin soils give way to the underlying geology with little ceremony. A 1995 inspection by Connolly concluded that the feature, while real enough, was agricultural rather than archaeological in the conventional sense. That distinction matters, though it is perhaps less clear-cut than it sounds. Field boundaries of this type, built from whatever stone lay conveniently to hand, are themselves a form of historical evidence, reflecting generations of farmers working within and around the natural grain of the land, clearing boulders and pressing them into service as boundary markers or low walls.
