There are no neat rows here, no formal boundary, just a loose and haphazard arrangement that speaks to a particular kind of burial practice, one that existed outside the usual rites of the Church. This is a cillín, the Irish term for an informal burial ground used historically for unbaptised infants, who were denied consecrated ground under Catholic canon law. Such places were typically situated at liminal locations, old ruins, field boundaries, or prehistoric monuments, and the choice of a cashel here is consistent with that pattern.

A cashel is a type of early medieval stone ringfort, a roughly circular enclosure defined by a dry-stone wall, used as a farmstead or defended dwelling. The one at Castletaylor provided the setting for this burial ground, its ancient walls lending a kind of borrowed sanctity, or at least separateness, to the spot. The site is documented by McCaffrey in 1952 and referenced again by O'Doherty in 1985, suggesting it had been known to local researchers for some decades before being formally recorded. The informality of the grave-markers, flat stones placed without apparent order, reflects both the clandestine nature of such burials and the grief of families who had few other options for their lost children.
