This one at Dooneens in mid-Cork does neither. It exists, essentially, as a mark on a map made in 1842, a small hachured circle indicating a roughly fifteen-metre circular enclosure that was already, presumably, on its way out of the landscape.

The Ordnance Survey's six-inch mapping of the 1840s was meticulous enough to record features that surveyors could see on the ground at the time, including low earthworks and slight earthen enclosures of the kind built throughout Ireland from the early medieval period onward. Such enclosures, often called ring-forts or raths, typically served as enclosed farmsteads, their banks and ditches defining a domestic space rather than a military one. Whatever stood at Dooneens was modest even by those standards, at around fifteen metres across, and at some point between the mid-nineteenth century and the present it was levelled entirely. No surface trace now remains.
