Man-made underground passage in Doon Upper

On summit of a circular hillock with bogland to N. A very poorly preserved oval platform (E-W 60m, N-S 50m) (GA073-073001-) defined by a scarp. A castle (GA073-073003-) is associated. There is also a local tradition of a 'cave' (possible Man-made underground passage, GA073-073002-) but no visible surface trace of it survives. The above description is derived from the published 'Archaeological Inventory of County Galway Vol. II - North Galway'.
