The platform itself is an unusual feature: a rectangular arrangement of upright slabs forming the boundary of a slightly elevated space, roughly 4.8 metres by 4 metres, its interior largely filled with small stones that include a notable quantity of quartz. Quartz held particular meaning in early Irish ritual contexts, appearing frequently at burial sites and sacred enclosures, which makes its presence here quietly suggestive rather than incidental.

The site sits within An Chathair Bhearnach, a name that translates roughly as the gapped or broken stone fort, indicating the presence of a cashel or dry-stone enclosure nearby. A cross-slab is exactly what the name suggests: a stone, usually a slab of local rock, onto which a cross has been carved or incised, often associated with early medieval monastic or devotional activity in Ireland. The combination of a defined ceremonial platform, upright boundary slabs, abundant quartz, and a carved cross-slab points toward a site that was used for religious purposes, possibly over a long period. The archaeological survey of the Iveragh Peninsula, compiled by A. O'Sullivan and J. Sheehan and published by Cork University Press in 1996, recorded this feature as part of its broader catalogue of the area's remarkably dense concentration of early monuments.
