The example at Toornanoulagh, in County Kerry, is one such site, a rath sitting in a corner of the Munster countryside that has thus far attracted minimal documentation in the public record.

A rath, to use the Irish term, is a roughly circular enclosure defined by an earthen bank and ditch, constructed during the early medieval period, broadly between the fifth and twelfth centuries. These were the farmsteads of their age, home to farming families and their livestock, the bank providing a degree of security against animal predators and rival neighbours rather than any serious military threat. Kerry, with its deeply rural character and relatively undisturbed agricultural land, retains a particularly good density of such monuments. The placename Toornanoulagh itself is likely derived from Irish, as most townland names in this part of Munster are, though without further documentation the precise etymology and local history of this particular enclosure remain elusive. What can be said is that its presence marks this patch of ground as a place of continuous human significance stretching back well over a thousand years.
