That positioning is no accident. The people who built this ringfort, known in Irish as a rath, chose the spot deliberately, as communities across early medieval Ireland routinely did, placing their enclosed farmsteads on any available patch of drier, firmer ground.

The ringfort at Carrowmanagh is a circular enclosure roughly 35 metres in diameter, defined by two earthen banks with a fosse, or ditch, running between them. The double-bank arrangement is relatively typical of more substantial raths, where the additional earthwork may have indicated the higher social standing of the occupant or simply provided extra security for livestock. The inner bank survives along the southern, western, and north-eastern arc of the monument; elsewhere the enclosure is defined by a scarp, a steep natural or cut slope that serves the same boundary function. The outer bank is most legible from the north-west around to the north-east. The site is recorded as being in fair condition, which, for an earthwork that has quietly endured in damp ground for potentially well over a thousand years, is no small thing.
