The site, known as Calluragh Burial Ground, functioned as a ceallúnach, a type of ancient burial ground used for unbaptised infants and others excluded from consecrated ground. Writing in 1879, a recorder named Brash noted that the site was devoted to the burial of unbaptised and baptised children up to the ages of six or eight months, adding plainly that no grown-up children or adults were ever interred there. The enclosure is roughly circular, defined by a low stony bank that has worn down considerably over the centuries, surviving to no more than 0.7 metres in height. Where the river curves closest to the site, along the north-eastern to eastern edge, the bank has disappeared entirely, as though the water itself marks the boundary. Inside, the ground is scattered with small boulders and upright grave-markers, modest and uninscribed.

Standing near the north-eastern edge of the enclosure is something considerably older than the burial ground's later use: an ogham stone, the ancient Irish script that uses a series of notches and lines cut along a stone's edge to record names and lineage. This stone, nearly 1.8 metres tall, carries an inscription on its north-western angle that the scholar Macalister read in 1945 as TIDONN[A] MAQ DOMNGINN, meaning roughly "Tidonna, son of Domhngeann." The opening two letters of the inscription are now buried below ground, and one character Macalister identified remains uncertain. On the western face of the same stone, someone at some point carved a large outline cross potent, a form of cross with arms that flare into a T-shape at each end. A small vertical groove marks where the right arm meets the shaft, and a single dot sits near the cross's centre. The combination of ogham inscription and Christian cross on one stone is a detail that speaks to a long period of use and layered significance, the early medieval world accumulating meaning on a single piece of Kerry sandstone.
