A rath, in its simplest form, is a roughly circular enclosure defined by one or more earthen banks and ditches, built primarily during the early medieval period, between roughly the fifth and twelfth centuries, and used as a farmstead and place of security for a family of some local standing. They are so common in the Irish landscape that they have faded, for many people, into background noise, noticed only as a raised ring in a field or a suspiciously circular hedge line.

What distinguishes any individual rath from the general mass of its kind is usually the particulars: who built it, how many banks it carries, whether it conceals a souterrain beneath its interior, and what happened to the land around it across the intervening centuries. For the rath at Cloondrinagh, those particulars remain, for the moment, largely unrecorded in the publicly accessible record. The site carries a monument classification, which confirms its recognition as an archaeological feature, but the documentary detail that would illuminate its specific character has not yet been made available. Clare is a county with a considerable concentration of surviving ringforts, many of them in townlands that saw relatively little agricultural intensification during the nineteenth and twentieth centuries, which allowed earthworks to persist where they might otherwise have been levelled.
