It is not a grave in any conventional sense. It is a gable-shrine, a form of early medieval monument made from two rectangular slabs leaning inward toward each other, capped at one end by a triangular stone, creating a miniature house-shaped structure. What makes this one quietly arresting is a detail in the western end-stone: a smoothly cut circular perforation, fifteen centimetres across, positioned near the base of the slab, with a deeply incised Latin cross carved above it. These circular openings, sometimes called soul holes or passage holes in popular tradition, appear on a number of early Irish monuments, though their original purpose is not fully understood. Here the combination of the hole and the cross gives the stone an almost deliberate, considered quality, as though it was made to be looked through as much as looked at.

The site sits within the early ecclesiastical enclosure of Cill Buaine, a place bound up with several competing saintly traditions. Locally, it is associated with St Buonia, also known as Beoanigh, who is reputed in oral tradition to have been a sister of St Patrick. Other accounts, recorded by O'Donoghue in 1893, suggest the site may have been founded instead by St Brendan, or by St Beoanus, a disciple of Brendan. None of these attributions can be resolved with certainty, but together they point to the kind of layered, contested sacred geography that characterises many early Christian sites along the Iveragh Peninsula. The leacht nearby, a word referring to a low rectangular cairn or mound used as a focus for devotion or commemoration, adds to the sense of a place that functioned as a node of pilgrimage or communal ritual. The gable-shrine stands just to the west of it. From this elevation, the views open out towards St Finan's Bay and, beyond that, the unmistakable silhouette of the Skelligs, which places this quiet mountain hollow firmly within the devotional landscape of early Kerry Christianity.
