No headstones mark it, no formal enclosure surrounds it, and to a passing eye it reads simply as a depression in the landscape, possibly a disused gravel pit. That ambiguity is part of what makes it worth pausing over.

Places like this are scattered across Ireland, known variously as cillíní or killeens, informal burial grounds used for centuries to inter unbaptised infants and others considered, under the conventions of the institutional Church, ineligible for consecrated ground. The locations chosen were often liminal: field boundaries, old earthworks, the edges of bogs, places that sat just outside the ordered world of the parish. At Cogaula, the site lies immediately north of a field boundary running northwest to southeast, which places it precisely in that kind of marginal, in-between space. Whether the hollow predates its use as a burial ground, or whether it was always understood in those terms, is no longer possible to say with certainty. The absence of grave-markers is common to sites of this type; burials were rarely if ever inscribed, and the knowledge of who lay there was carried in local memory rather than stone.
