No stone, no hollow in the earth, no trace of any kind survives at the surface. The site exists almost entirely as memory.

The ground in question lies within a ringfort, one of the roughly 45,000 or so circular earthwork enclosures scattered across Ireland, most dating from the early medieval period. These were typically the defended farmsteads of prosperous families, and they were never quite forgotten by the communities that grew up around them. Over time they accumulated layers of association, folklore, and in many cases use. Children's burial grounds, known in Irish as cillíní, were places set aside for unbaptised infants and others considered ineligible for consecrated ground under Catholic Church practice. They appear across Ireland in a wide variety of locations, old ringforts among them, perhaps because such places already carried a sense of age and apartness. At Tonroe, local tradition is clear that such burials took place here, even if the archaeology cannot now confirm it.
