This is a rath, the most common type of early medieval enclosure in Ireland, typically built between roughly the fifth and twelfth centuries as a defended farmstead for a single family or small household. Thousands survive across the country in varying degrees of legibility, and this one, about thirty metres in diameter, is neither dramatic nor derelict; it simply persists, holding its shape on the hillside at Urraghry.

A rath of this kind would originally have consisted of an earthen bank, sometimes topped with a timber palisade, encircling a domestic interior where people lived, kept animals, and stored food. This example is defined by two concentric banks with a fosse, or ditch, cut between them, a double-bank arrangement that suggests a degree of additional effort or status on the part of whoever commissioned its construction. The banks are heavily vegetated now, their profiles softened by centuries of growth, but the basic form remains intact enough to be read as a coherent structure rather than a vague earthen swell.
