It is easy to miss, and that near-invisibility is part of what makes it worth attention. This is a rath, the Irish term for a roughly circular earthwork enclosure, typically dating from the early medieval period, which would once have enclosed a farmstead or small settlement. Thousands of them survive across Ireland in varying states of preservation; this one falls into the poorly preserved category, its subcircular outline measuring approximately 31 metres on its longer north-northeast to south-southwest axis and 26.5 metres across.

The site sits within land that formed part of Moorfield Demesne, a detail that hints at later layers of history overlaying the early medieval one. A demesne was the land attached to and worked directly from a large house or estate, and the survival of a rath within such a landscape suggests the earthwork was either left alone as a field boundary curiosity or simply never worth the effort of levelling. Immediately to the east of the rath, a field wall running northeast to southwest runs close alongside it, one of those small topographical coincidences that often hints at how older landscape features quietly shaped the agricultural patterns that followed them.
