Known in Irish as a ráth, this type of monument is among the most common survivals of early medieval Ireland, a circular enclosure defined by one or more earthen banks and ditches that once enclosed a farmstead, a family, their animals, and whatever small measure of security a raised boundary could offer. There are tens of thousands of them recorded across the island, yet each occupies a specific patch of ground chosen deliberately, often on a slight rise with good sightlines, and each carries the faint imprint of a decision made sometime between roughly the third and tenth centuries.

Kilfarboy parish, which takes in the area around Miltown Malbay on the Atlantic coast of Clare, is old ground in every sense. The name itself derives from the Irish eaglais, meaning church, combined with a personal name, pointing to an early ecclesiastical settlement in the area. The west Clare landscape is scattered with the residue of early Christian and pre-Christian activity, from fulacht fiadh cooking sites to standing stones, and ringforts are a recurring feature of the townlands throughout the parish. A ráth of this kind would typically have served as the enclosed homestead of a farming family of some local standing, the bank and ditch functioning less as a fortification in any military sense and more as a marker of territory and a deterrent against cattle raiders, which in early medieval Ireland amounted to much the same thing.
