This natural formation, which slopes gently southward, may once have served as the foundation for a fortified bawn; a defensive wall that would have enclosed and protected the settlement within. Archaeological evidence suggests the platform supported at least two late-medieval buildings on its northern half, with additional structural remains scattered across the site including a briar-covered cairn and house foundations in the southeast corner.

The platform’s edges tell their own story of human modification over centuries. The northern side features a 1.5-metre high scarp with an old quarry face at its base, topped by a grassed-over stone wall that might relate to a building marked on 1940s Ordnance Survey maps. The eastern edge rises more dramatically at 2.2 metres, with a retaining wall built halfway along to prevent erosion. Traces of a linear wall or bank along the western side, extending around to meet the northern edge, support the theory that this entire platform was once encircled by protective walls.

Local tradition adds an intriguing layer to the site’s history, as residents know it as ‘Lochlann Riabhach Ó hEithir’s House’. Some historians, including Breen and Ua Cróinín, have suggested this location might actually be the site of the elusive Ballycasheen Castle, though definitive proof remains tantalisingly out of reach. The various building foundations visible across the platform, some appearing on 19th-century maps and others lost to time, hint at centuries of continuous occupation and adaptation of this strategic elevated position.
