The enclosure is a rath, the most common type of early medieval monument in Ireland, typically consisting of a roughly circular bank and ditch thrown up to define a defended farmstead. What makes this one quietly arresting is its position: from its elevated ground, the land opens out to the east, south-west, and north in long, unobstructed views, the kind of visibility that was almost certainly the point.

The earthwork measures roughly 47 metres along its north-west to south-east axis and 27 metres across the other way, giving it a noticeably oval plan rather than the more symmetrical form seen at many comparable sites. That slight elongation, following the natural contour of the rise, suggests the builders were working with the land rather than imposing a geometry upon it. On aerial photography the enclosure resolves into a tree-lined ring set within ordinary farmland, the kind of feature that reads as a field boundary or a windbreak until you know what you are looking at.
