The example at Shanganagh in County Clare belongs to a type known as a rath, a roughly circular enclosure defined by one or more earthen banks and ditches, built during the early medieval period, roughly between the fifth and twelfth centuries. These were not primarily military structures. They served as farmsteads, the defended homesteads of farming families, enclosing a central living area against livestock theft and the ordinary hazards of rural life.

Clare is particularly well-furnished with such monuments, sitting as it does in a landscape where early medieval settlement left deep marks on the ground. The county's geology, a mix of limestone plains and more sheltered inland terrain, suited the dispersed, family-based farming patterns that ringforts represent. Each rath would typically have sheltered a single household or small kin group, with the bank and ditch serving as much as a social boundary, marking status and territory, as a physical defence. The Shanganagh example represents one node in what was once a dense network of such sites across the region, most of them long since reduced to faint earthwork traces by centuries of agricultural activity.
