It is easy to walk past without knowing what it is, the ground cover thick, the stones modest and low, the whole area barely larger than a modest living room.

The site is recorded in the Ordnance Survey Letters, a remarkable nineteenth-century project in which scholars travelled Ireland documenting the history, folklore, and topography behind place names, as 'a burying ground for children'. This identifies it almost certainly as a cillín, a type of informal or unconsecrated burial ground traditionally used for unbaptised infants, who were excluded from consecrated ground under older Catholic practice. Such sites are found across Ireland, often on liminal ground, at townland boundaries, on hillocks, or near ancient earthworks. The Killafeen example takes a D-shaped form, roughly 6.5 metres east to west and 5 metres north to south, with a field wall marking its northwestern limit. Within that boundary, a number of small set stones identify individual graves, though the site is poorly preserved and the vegetation has largely reclaimed it.
