Ringforts, known in Irish as raths, were the most common form of rural settlement in early medieval Ireland, typically consisting of a circular area enclosed by one or more earthen or stone banks and ditches. They served as farmsteads, the homes of farming families and minor lords, and the sheer number of them still visible across the country, estimated in the tens of thousands, speaks to how thoroughly they once defined the Irish countryside.

Furroor lies in Clare, a county whose limestone terrain has preserved an unusual density of early medieval and prehistoric remains. The rath here would have functioned much as its counterparts across Ireland did, providing a defended enclosure for a household, its animals, and its stores. The bank, whether still clearly visible or softened by centuries of agriculture, marks the boundary between the domestic interior and the world beyond it. These sites were not fortresses in any military sense but statements of ownership and order, the fundamental unit of early Irish social organisation made physical in the earth.
