The feature is a leacht, a type of low commemorative or devotional platform associated with early Irish monasticism, typically used as a focus for prayer or veneration at a saint's site. This particular example is modest in scale, a subrectangular platform measuring roughly 3.2 metres north to south and 3.6 metres east to west, its edges defined by upright slabs set end-to-end. What makes it quietly unusual is the arrangement of hollows around it: rectangular depressions in the northwest corner and just outside the southern edge, each partially bordered by their own upright slabs, and a larger oblong hollow to the north measuring around 2.5 by 5 metres, with further slabs marking its upper western edge.

The leacht sits on the north side of the oratory recorded at this site on Long Island, one of the smaller inhabited or formerly inhabited islands scattered along the Kerry coast. Early Christian communities in Ireland frequently established themselves in such marginal, island locations, and the combination of oratory and leacht here follows a pattern seen elsewhere across the west of Ireland, where monks would construct small stone churches alongside outdoor devotional structures for ritual use or burial commemoration. The relationship between the platform, the surrounding hollows, and the raised area of irregular plan to the north has not been fully explained, but the grouping suggests this was a place of some sustained ceremonial or liturgical significance within what would have been a small monastic enclosure. The archaeological survey of the Iveragh Peninsula, published by Cork University Press in 1996 and compiled by Aidan O'Sullivan and John Sheehan, provides the detailed measurements and layout that allow the structure to be understood in its spatial context.
