Long before it became associated worldwide with a particular gold ring, the Claddagh was a fishing settlement on the western edge of Galway city, widely regarded as one of the oldest continuously inhabited communities in Ireland. It sat just outside the old town walls, separated from the walled Anglo-Norman borough by the River Corrib, and it operated for centuries as a largely self-governing village with its own elected king, its own laws, and its own fishing customs. That separateness left traces, and among them is an enclosure whose presence in the archaeological record points to the layered, pre-modern occupation of this small and frequently overlooked patch of ground.

An enclosure, in the archaeological sense, is simply a defined area bounded by a bank, ditch, wall, or combination of these, and such features can date from the prehistoric period right through to the medieval. Their purposes vary considerably: some enclosed settlements, some were associated with early ecclesiastical sites, others served agricultural or defensive functions. In a place like the Claddagh, where generations of fishing families lived in tightly clustered thatched cottages that were almost entirely cleared in a controversial programme of demolition and rebuilding in the 1930s, the survival of any earlier structural trace is significant. The community that existed here was Gaelic-speaking and culturally distinct from the merchant town across the river, and the physical evidence of earlier occupation sits underneath and alongside that more recent history.
