The rath at Carrowcore, in County Clare, is one such site: a circular earthwork enclosure, most likely dating to the early medieval period, of the kind that once served as a defended farmstead for a family of some local standing. The word "rath" refers specifically to an earthen ringfort, typically defined by one or more concentric banks and ditches, as distinct from a stone-built cashel. Clare, with its mix of limestone upland and fertile lowland, is well populated with examples.

Beyond its classification and location, the documentary record for this particular site is thin. What can be said with confidence is that ringforts in general were built and occupied roughly between the fifth and twelfth centuries, functioning as enclosed homesteads rather than military fortifications in any large-scale sense. The enclosing bank offered protection for livestock as much as for people, and the interior would typically have held a timber or wattle house, outbuildings, and perhaps a souterrain, an underground stone-lined passage used for storage or refuge. The place-name element "Carrow" derives from the Irish "ceathrú", meaning a quarter, a townland division that itself speaks to the long-settled agricultural character of this part of Clare.
