The result is a rath, the Irish term for an earthen ringfort, a circular enclosure formed by a raised bank and a surrounding ditch that once marked the boundary of a farmstead and its household. Thousands of these survive across Ireland, yet each one carries its own particular logic, shaped by the land it sits on and the people who built it.

This example measures roughly 28 metres across from east to west and sits on a south-east-facing slope, its bank rising to 2.35 metres in height. That is a substantial earthwork, built to be seen and felt as a boundary. Parts of the bank retain stone facing, suggesting the builders had access to local material and were not simply piling up soil. Around much of the perimeter runs an external fosse, a defensive ditch, surviving to a depth of 0.55 metres, tracing an arc from the west-south-west to the north-north-east. A gap of about 2 metres in the eastern side of the bank marks what was almost certainly the original entrance. Raths of this kind were typically the enclosed farmyards of early medieval Ireland, home to a single family of some local standing, their livestock sheltered inside the bank at night, the ditch providing an added deterrent against cattle raids and opportunistic theft.
