The one at Corebeg, in County Clare, is among the quieter examples, a rath sitting in a landscape that has long since grown around it without much fuss.

A rath, to use the Irish term, is a roughly circular enclosure defined by one or more earthen banks and ditches, built during the early medieval period, broadly between the fifth and twelfth centuries. They functioned primarily as farmsteads, the raised banks offering a degree of protection for a family, their livestock, and their stores. Clare is particularly well supplied with them, the county's mix of lowland pasture and limestone upland having supported dense early medieval settlement. Corebeg, a small townland whose name likely derives from the Irish for a small boggy hollow, would have been part of that wider pattern of dispersed rural life, each rath a self-contained domestic unit within a network of similar enclosures across the territory.
