What survives are the foundations of a structure tentatively identified as an oratory, a term used in early Irish Christianity for a small, private or monastic place of prayer, often no larger than a single room. This one is remarkably modest even by those standards, measuring roughly 2.7 metres east to west and 2.3 metres north to south, with walls surviving to only half a metre in height and about 1.5 metres thick.

The entrance, on the western side, is just 0.7 metres wide, flanked on either side by a large upright slab. That arrangement, a narrow western doorway marked by standing stones, is consistent with early medieval ecclesiastical building practice in the west of Ireland, where simple enclosures and small stone oratories were once scattered across islands and promontories. The structure sits to the north of an internal enclosure that forms part of the wider site, and close to what appears to be the centre of that complex. Its classification as a "possible" oratory reflects genuine uncertainty; without excavation, the building's function and date remain open questions, though the form and setting are suggestive of early Christian activity on the island.
