The one at Kilfearagh, in County Clare, sits quietly in this vast category, a circular enclosure of the kind that served as a farmstead or family settlement during the early medieval period, roughly between the fifth and twelfth centuries. A rath, as this type is known, typically consisted of one or more earthen banks and ditches arranged in a ring, enclosing a space where people lived, kept animals, and stored food. The name Kilfearagh itself carries older layers, the prefix "Cill" pointing to an early ecclesiastical association, suggesting this corner of Clare had some significance long before anyone thought to record it systematically.

Beyond its classification and location, the specific history of this particular site remains largely undocumented in any publicly accessible form. What can be said is that Clare is unusually rich in early medieval remains, lying as it does in a region where the land was divided and farmed intensively during the period when ringforts were most actively in use. Many such enclosures were built by free farming families, functioning as both home and statement of ownership in a society where land tenure carried considerable social weight. Some were later adapted, abandoned, or absorbed into the field systems of subsequent centuries, which is part of why so many survive, having been left alone rather than demolished.
