The example at Cahiracon, in County Clare, is one such site, a circular earthwork enclosure of the kind that would have served as a defended farmstead, typically dating somewhere between the seventh and twelfth centuries. A rath, as this type is properly called, consists of one or more earthen banks and ditches thrown up around a central living area, home to a family of some local standing in early Christian Ireland.

Cahiracon itself sits along the southern shore of the Shannon Estuary, a part of Clare with deep layers of history folded into its landscape. The placename derives from the Irish meaning something close to "stone fort of the promontory", which suggests the area was recognised as a place of enclosure or defence long before anyone wrote it down. Beyond its location and classification as a rath, the specific details of this particular site, its dimensions, its condition, any finds or features recorded within it, remain to be fully documented in publicly accessible form.
