The example at Clenagh in County Clare is a rath, the term used for a ringfort constructed primarily from earthworks rather than stone, typically comprising one or more circular banks and ditches enclosing a central living area. During the early medieval period, roughly the fifth to the twelfth centuries, these enclosures served as farmsteads for families of varying social rank, the size and number of surrounding banks broadly reflecting the status of whoever lived within.

Clenagh sits in a part of Clare with deep layers of early settlement history, and a rath in this landscape would have been a working agricultural homestead rather than a fortification in any military sense. The bank and ditch arrangement of a typical rath was intended to manage livestock, define territory, and offer a modest degree of protection from opportunistic raiding. Inside, a family would have kept their dwelling house, outbuildings, and perhaps a souterrain, an underground stone-lined passage used for storage or as a place of refuge. Over centuries, many such sites were absorbed quietly into farmland, their banks reduced by ploughing or simply softened by time, which makes those that survive with any clarity worth pausing over.
