Known in Irish as a rath, a ringfort is an enclosed farmstead of the early medieval period, typically circular, defined by one or more earthen banks and ditches. They were the homes of farming families, places where people kept cattle, stored grain, and went about ordinary lives somewhere between the fifth and twelfth centuries. Ireland has tens of thousands of them, yet each occupies a specific patch of ground with its own particular history, and the one at Feagh is no exception.

The townland of Feagh lies in County Clare, a county whose limestone geology and complex pattern of small landholdings made it fertile territory for exactly this kind of enclosed settlement. The rath at Feagh would have served as a defended homestead, its raised bank offering both a practical barrier against livestock straying and a social signal of status and permanence. The earthworks of such sites are often all that survives above ground, the original timber structures and domestic debris long since dissolved into the soil, though excavations elsewhere in Ireland have recovered evidence of houses, hearths, souterrains (underground stone-lined passages, likely used for storage or refuge), and metalworking.
