The one at Lattoon, east of the Ahascragh-Ballygar road in County Galway, is roughly 80 metres along its longer axis and 35 metres across, and its irregular form raises a question that the ground itself cannot quite answer: is that curved wall a modern convenience, or does it trace the ghost of something much older?

Archaeologists suspect the latter. The curving perimeter may preserve a segment of an early ecclesiastical enclosure, the kind of roughly circular boundary that defined a sacred or monastic precinct in early medieval Ireland, often the oldest surviving trace of a religious site. The graveyard, though modern in its present form, was not mapped with any clarity on the first edition of the Ordnance Survey six-inch sheets, named but not precisely delineated, which hints at a place that existed in local knowledge more than in official record. Within its bounds lie the sites of two post-medieval Roman Catholic chapels, pointing to the long use of this ground for worship long after any early monastery may have faded. More unexpectedly, there is also a souterrain here. A souterrain is an underground stone-lined passage or chamber, most commonly associated with early medieval settlements in Ireland, where they served for storage, refuge, or both. Finding one within a graveyard context, possibly beneath or beside later chapel remains, adds another layer to a site that has clearly accumulated purpose across many centuries. Burials on the site run from the eighteenth century through to the twentieth, meaning the ground has been in continuous use as a place of the dead for at least three hundred years.
