The rath at Carrowreagh in County Clare is a case in point: a monument old enough to have outlasted entire civilisations, sitting quietly in the Clare countryside with almost nothing written about it in the public record.

Ringforts, known variously as raths or lios depending on region and local tradition, were the dominant form of rural settlement in early medieval Ireland, broadly from around the fifth to the twelfth centuries. They typically consisted of a circular area enclosed by one or more earthen banks and ditches, and served as farmsteads for families of varying social rank. The more banks a fort possessed, the higher the status of its occupants was thought to be. In County Clare, the limestone-rich landscape of the Burren and its surrounding lowlands is particularly dense with these structures, many of them still visible as earthwork rings in fields that have been farmed continuously for over a millennium. The place-name Carrowreagh derives from the Irish, likely referring to a grey or worn quarter of land, suggesting a townland with a long memory of agricultural use. Beyond the fort's existence and its classification as a rath, the documentary record currently holds its details close.
