Known locally as a rath, this type of enclosure is essentially a circular earthwork, a raised bank and ditch surrounding a farmstead, built to define territory, protect livestock, and signal the presence of a family of some standing. Ireland has tens of thousands of them, yet each occupies its own particular ground, and the ones out along Loop Head occupy ground that feels genuinely remote even now.

Kilbaha is a small coastal settlement near the peninsula's end, a place more associated with the nineteenth-century story of the Little Ark, a mobile chapel built to allow Mass to be celebrated on the foreshore beyond landlord control, than with prehistoric or early medieval remains. The ringfort predates all of that by well over a thousand years. Raths of this type were most commonly constructed between roughly the fifth and twelfth centuries, during the period when Ireland's landscape was shaped less by towns than by scattered farmsteads, each one ringed by its earthen boundary. The particular history of this example, its builders, its dimensions, and whatever archaeology may lie beneath its banks, remains to be fully documented in the public record.
