The ground inside shows nothing now, no markers, no mounds, no trace of what was once placed here, yet the site was recorded as a children's burial ground, one of the many scattered across Ireland that speak to a long and quietly sorrowful tradition.

The enclosure itself is thought to be a cashel, a type of early stone-walled ringfort typically dating from the early medieval period, though the term "possible" signals that its origins and original purpose remain uncertain. Cashels were built as enclosed farmsteads or places of habitation, their thick dry-stone walls demarcating a domestic world. At some point, this particular enclosure at Tawnaghbeg took on a different function. Writing in 1969, a researcher named Aldridge recorded that the interior had been used as a burial ground for children. These sites, known in Irish as cillíní, were used for the interment of unbaptised infants and others who, under Catholic practice of the time, could not be buried in consecrated ground. Ringforts, old enclosures, and liminal landscape features were commonly chosen for this purpose, places that carried their own ancient gravity and stood apart from the parish churchyard. By the time of Aldridge's note, no surface evidence of graves remained, and that absence has only deepened in the decades since.
