Enclosures of this kind are among the most common, and most easily overlooked, features in the Irish landscape. They are typically roughly circular boundaries, formed from earthen banks, ditches, or stone walls, and they served a wide range of purposes across many centuries, from the enclosure of early farmsteads to the demarcation of ecclesiastical or ceremonial ground. Without more specific detail it is not possible to say which category this particular example falls into, but its presence in Rahoon, a townland that sits between the city and the older rural parish landscape to the west, gives it a quietly anomalous quality, a fragment of pre-modern land use embedded in a place that has changed enormously around it.
