No inscriptions mark them. The enclosure itself, measuring roughly 29 metres north to south and 27 metres east to west, is bounded by a low wall of upright slabs. The quiet geometry of the place, and those stones, signals immediately that this is a cillín, the Irish term for an unconsecrated burial ground set aside for unbaptised infants.

Cillíní are found across Ireland in their hundreds, occupying threshold spaces in the landscape, old boundaries, liminal ground near water, the margins of townlands. Catholic doctrine held, until relatively recently, that unbaptised children could not be buried in consecrated ground, and so communities maintained these separate, informal cemeteries for generations. The Kylemore example sits on a hillslope roughly a hundred metres south of the road, looking out over the river below. The slab-built boundary wall, low and plain, encloses a space that would have been known and quietly tended by the local community, its location passed down through memory rather than recorded on any official register. The small stones set into the interior are the only markers, modest and unlettered, placed by families for whom formal commemoration was not an option.

The site overlooks the Kylemore River, and the surrounding landscape gives some sense of why this particular slope was chosen. Proximity to water, a degree of seclusion from the main road, and a naturally bounded piece of hillside all feature in the siting of cillíní elsewhere in the west of Ireland. The enclosure is visible from the road, though its significance is easy to miss without knowing what to look for.
