A few of those stones, where the overgrowth has receded enough to reveal them, turn out to be uncut limestone blocks. The informality is the point. This is almost certainly a cillín, a children's burial ground, of the kind once found across rural Ireland wherever unbaptised infants, and sometimes others considered outside the formal rites of the Catholic Church, were laid to rest in unconsecrated ground.

Cilliní were often sited in places already marked out as old or liminal: ruined churches, ancient earthworks, the margins of bogs. Here, the choice of a ringfort, a type of enclosed farmstead typically dating to the early medieval period, follows that pattern. The townland name itself adds weight to the identification. Caltraghlea derives from the Irish, and names of this kind frequently preserve a memory of a place used for burial long after the practice had faded and the markers had been swallowed by grass and moss. Without such linguistic traces, sites like this one can become almost invisible, read by a passing eye as nothing more than a damp hollow with a few loose stones.
