The example at Ballymacnevin in County Clare is one such site, a rath, which is the Irish term for a roughly circular enclosure typically formed by an earthen bank and external ditch, constructed during the early medieval period, broadly between the fifth and twelfth centuries. These were the farmsteads of their age, home to a single family and their livestock, and the circular form was less about military defence than about defining a boundary, social as much as physical, between the household and the world outside it.

Clare is particularly well furnished with such monuments. The county sits within a landscape that supported dense rural settlement throughout the early medieval period, and the limestone terrain of much of the region has, in places, preserved earthworks that might elsewhere have been lost to centuries of ploughing or drainage improvement. Ballymacnevin as a placename contains the Irish element mac, suggesting an association with a particular family or lineage, though the specific history of this individual site, its dimensions, condition, and any finds or features recorded during survey work, is not currently available in the public domain.
