It measures roughly nine metres north to south and seven metres east to west, and its surface is subcircular, gently humped, and partly obscured by stone cleared from the surrounding fields over the years. Nothing marks it out as anything other than a feature of the agricultural landscape. Yet it is a children's burial ground, a cillín, one of the quiet, largely unmarked burial places where, for centuries, unbaptised infants were interred outside the boundaries of consecrated ground.

Cillíní (the singular is cillín, sometimes anglicised as killeen) were used across Ireland from at least the medieval period and continued in use well into the twentieth century. Catholic doctrine held that unbaptised children could not be buried in consecrated ground, and so families interred them in liminal spaces, old ringforts, the edges of bogs, early Christian enclosures, or low mounds like this one. The grief was real but often unacknowledged publicly, and the sites themselves were rarely given formal markers. What makes this particular example quietly notable is that it sits approximately 450 metres north-west of another children's burial ground, suggesting that this part of Galway carried a concentration of these sites, each one reflecting the same community need and the same theological exclusion, generation after generation.
