The example at Carrowmoremoy, in County Mayo, is one such site, a rath sitting in a landscape whose very placename hints at something older beneath the surface. Carrowmoremoy derives from the Irish, broadly meaning the great plain quarter, and it is the kind of townland where the ground has been occupied, farmed, and fought over across many centuries.

A rath is a circular enclosure, typically defined by one or more earthen banks and ditches, built during the early medieval period in Ireland, roughly between the fifth and twelfth centuries. They functioned primarily as farmsteads, the defended homesteads of farming families of varying social rank, though some were also used for assembly or as markers of territorial boundary. Mayo contains a considerable number of such monuments, and Carrowmoremoy sits within a county whose archaeology ranges from the megalithic field systems of the Céide Fields to the early Christian remains scattered across its boglands and coastal margins. The rath at Carrowmoremoy belongs, in other words, to a long and layered sequence of human settlement in the west of Ireland, even if its own specific story remains, for the moment, difficult to access in detail.
