These places occupy a particular and sorrowful corner of Irish social history. Because the Catholic Church long denied formal burial rites to unbaptised children, families turned instead to liminal spaces, old ringfort ditches, the margins of fields, or small enclosures passed down in local memory, to lay their infants to rest. The practice continued in parts of rural Ireland well into the twentieth century.

Cillíní are found across the country in their hundreds, many unmarked on any official map and known only to local families. They tend to occupy ground that felt ancient or set apart, sometimes overlapping with earlier prehistoric enclosures or early medieval ecclesiastical sites, though the connection is not always deliberate. The one at Creevymore has been formally recorded as an archaeological monument, placing it within a landscape that contains, as much of County Sligo does, layer upon layer of human activity reaching back to the Neolithic. Beyond its designation and location, the specific history of this particular ground, who established it, how long it was used, and what physical traces remain, is not currently in the public record.
