The example at Corbally in County Clare belongs to the rath tradition, a term referring to a roughly circular enclosure defined by one or more earthen banks and ditches, raised during the early medieval period, roughly between the fifth and twelfth centuries. These were not primarily military structures; most served as farmsteads, the defended homesteads of farming families who needed to protect livestock as much as people. That so many survive, even in partial form, speaks to how deeply they were woven into the pattern of daily rural life for centuries.

Clare is particularly well furnished with such monuments, sitting as it does within a region where early medieval settlement was dense and where the underlying limestone geology often preserved earthworks that might elsewhere have been ploughed away. Corbally, as a placename, derives from the Irish An Corbally, meaning an odd or irregular townland, a designation that hints at the way land was divided and named long before any map was drawn. The rath itself would once have formed the centre of a small agricultural holding, its banks demarcating the boundary between the managed domestic space within and the open farmland beyond.
