These circular earthwork enclosures, known in Irish as raths, were the farmsteads of early medieval Ireland, typically consisting of a raised interior platform ringed by one or more earthen banks and ditches. They were domestic rather than military in character, built to shelter a family, their livestock, and their stores from the ordinary hazards of rural life. Ireland has tens of thousands of them, yet each one occupied a particular patch of ground for particular reasons, chosen by a particular household whose name has long since dissolved into the general past.

Clenagh is a small townland in the barony of Bunratty Lower, in the broader lowland country of east Clare between the Shannon estuary and the Burren uplands. The area was settled continuously from prehistoric times through the early Christian period and beyond, and ringforts are a common feature of the agricultural landscape here, as they are across much of Munster. The rath at Clenagh would have been constructed somewhere between the sixth and twelfth centuries, the long era when this type of enclosed farmstead was the standard unit of rural settlement across Ireland. What distinguished one rath from another was often the number of enclosing banks: a single bank suggested a modest farming household, while two or three concentric rings implied greater wealth or status.
