The example at Curraheen in County Kerry is one such site, a rath sitting in a county whose terrain, from the Dingle Peninsula to the Iveragh uplands, preserves an unusually dense concentration of early medieval settlement remains.

A rath, to use the Irish term, is a roughly circular enclosure defined by one or more earthen banks and ditches, typically dating to the early medieval period, broadly between the fifth and twelfth centuries. They functioned primarily as enclosed farmsteads, the home and working space of a family of some local standing, with the banks offering a degree of protection for livestock as much as for people. Kerry's landscape, with its mix of sheltered valleys and elevated ground, made it well suited to this kind of dispersed agricultural settlement, and raths here were often positioned to command a view of surrounding land or to sit near reliable water sources. The Curraheen example belongs to this wider pattern, one node in a network of early medieval life that once covered the peninsula and its hinterlands.
