No stones, no enclosure, no trace. The site at Foildarrig exists almost entirely as a name and a memory, its purpose preserved in writing long after any physical evidence had gone.

These places are known in Ireland as cillíní, informal burial grounds used for centuries to inter those who could not be admitted to consecrated ground under Catholic Church law. Unbaptised infants were the most common occupants, though stillborn children, and sometimes others considered to exist outside the bounds of formal parish life, were also buried in such spots. The Ordnance Survey Namebooks of 1840 describe Foildarrig precisely in these terms, as a place for "still born infants or children dying without baptism." The location sits close to a bowl-barrow to the southwest, a type of prehistoric burial mound characterised by a circular mound within a surrounding ditch, which suggests the upland around Foildarrig had been used as a place set apart from ordinary life across a very long span of time. The proximity of the cillín to an earlier church site adds another layer; these informal grounds were often deliberately placed near, but not within, ecclesiastical enclosures.

What makes Foildarrig quietly affecting is precisely its absence. The 1840 record names it and describes its function with matter-of-fact brevity, but by the time archaeological fieldwork was carried out, nothing visible remained in the vicinity of the church site. The landscape has absorbed it entirely, leaving only the documentary record as evidence that families once came here to bury their smallest dead in ground that the Church would not consecrate for them.
