It is a cillín, the Irish term for an unconsecrated burial ground used for unbaptised infants, and for centuries these quiet, marginal places received the children whom the Catholic Church held could not be interred in consecrated soil. The theological reasoning has long been abandoned, but the sites remain, and this one sits in ordinary farmland with almost nothing to mark it out.

The Ordnance Survey six-inch map of 1842 labels it plainly as a Children's Burial Ground, which is itself a small act of acknowledgement at a time when such places were often simply absorbed into the landscape without comment. The enclosure takes the form of a low, almost entirely levelled earthen bank following a circular line, the kind of boundary that once would have set the space apart from the surrounding fields. No grave markers have been recorded here, which is not unusual for a cillín. Burials were typically informal, sometimes carried out at night, and the families involved often had neither the means nor, in some cases, the social permission to mark the graves openly. What remains is essentially the outline of a boundary and the knowledge of what it once contained.
