It occupied a small, artificially raised mound, roughly ten metres by seven and a half metres, and was marked by modest, moss-covered grave-stones set into the earth. Then, sometime around the mid-2000s, it was cleared away to make room for a house. No surface trace survives.

The site belonged to a tradition of burial that was once widespread across Ireland. Children who died without baptism were, under the theological conventions of the time, excluded from consecrated ground, and so communities created their own informal sacred spaces for them. These places are known in Irish as cillíní, and they were often sited on liminal ground, old boundaries, or pre-existing earthworks. The mound at Killeelaun fits that pattern. An artificially raised platform of that size, in otherwise low-lying terrain, would have stood out gently in the landscape, and its selection as a burial place may well have drawn on older associations with the ground itself. No burials had taken place there within the century before its destruction, suggesting it had passed quietly out of active use, though the moss on the grave-markers points to a site that had been tended or at least left undisturbed for some time before the end came.

What makes this particular entry quietly sorrowful is its finality. Many cillíní survive, if only partially, as slight rises in a field or a cluster of unmarked stones in a hedgerow. This one does not. The record of it exists only because local people remembered it and described it before it was gone.
