Recorded in the mid-twentieth century as a ceallúnach, the Irish term for a children's burial ground or unconsecrated burial place typically used for unbaptised infants and others excluded from churchyard burial, it was noted by a researcher named Henry in 1957 as being situated roughly ninety metres north-east of a ruined oratory. Even then he described it as offering nothing in the way of visible features. Today, nothing at all can be seen at the surface.

What makes the site quietly compelling is its possible connection to a far more dramatic event. The Ordnance Survey Name Books for the parish of Kilcrohane record that a disused burial place on Scariff Island was the resting place of Francis O'Sullivan, Provincial of the Irish Franciscan Order, who was executed on the island in 1653. If this identification is correct, then a senior figure in the Irish Catholic church in the years following the Cromwellian conquest met his end here and was buried in a plot already marginal to the formal rites of the faith he served. The broader ecclesiastical site on the island, reached by a path climbing from the landing place at Cuas na Naomh on the north-east shore, includes the remains of a terraced oval enclosure containing the oratory, a burial ground, and a nineteenth-century house. Outside the enclosure to the south-west there is also a souterrain, an underground stone-lined passage of the kind associated with early medieval Irish settlements, sometimes used for storage or refuge. The ceallúnach sits apart from all of this, to the north-east, and whatever physical form it once had has long since gone.
