The only substantial record of it is a small circular shape on the 1835 edition of the Ordnance Survey six-inch map, labelled in gothic lettering simply as a "fort". Nothing is visible at ground level today; no earthwork, no bank, no ditch. Yet the cartographic evidence suggests this was once a ringfort, a type of circular enclosed settlement used throughout early medieval Ireland, typically defined by one or more earthen banks and ditches enclosing a domestic space. The external diameter recorded on that map, somewhere between twenty-five and thirty metres, is modest even by ringfort standards.

The 1835 OS mapping was the first systematic large-scale survey of Ireland, and its surveyors were careful to note earthworks and enclosures that local people still recognised and named. That this site was already described as a "fort" rather than given a more functional label suggests it had already passed out of active use long before the surveyors arrived, remembered more as a landmark than a structure. Its position on a gentle rise, roughly thirty metres from the lough shore, fits a pattern common to early medieval settlement, where slight elevation offered drainage and visibility without retreating far from water. What happened to the physical remains in the intervening centuries is not recorded; gradual erosion, agricultural levelling, or simply the slow subsidence of earthen banks back into the surrounding land are all possibilities for sites of this kind.
