What looks, at first glance, like an unremarkable field is in fact a cillín, a children's burial ground of the sort once found across rural Ireland. These sites were used to inter unbaptised infants and others considered ineligible for consecrated ground, a practice rooted in Catholic doctrine and sustained across several centuries by social necessity and quiet grief.

The burial ground at Cregganore occupies a roughly rectangular, unenclosed area of approximately fourteen metres east to west and six metres north to south. Clearing of the western half revealed three parallel rows of small, undressed stones, irregularly spaced, marking graves oriented east to west in the traditional Christian manner. The site sits some fifteen metres to the south-west of a holy well, that characteristic feature of the Irish landscape where pre-Christian and Christian devotion long overlapped, and a church once stood roughly forty-eight metres to the north-north-west. The proximity of all three elements, church, holy well, and children's burial ground, suggests a site of sustained local significance, even if the cillín itself remained deliberately apart from the consecrated land of the church.

The unenclosed nature of the site is typical of cillíní generally. There are no walls to define it, no markers a casual eye would immediately read as a graveyard. The three rows of small set stones, modest and undressed, are the only surviving sign of the burials beneath. That so much is legible at all, given the simplicity of the grave markers, is a reminder of how much these sites depended on local memory rather than formal inscription to preserve their meaning.
