An ancient enclosure, roughly 38 metres in diameter, sits straddling the boundary between Wicklow and Wexford, with the greater part of it lying in Wexford and only its northern edge creeping across into Wicklow territory. That boundary-straddling quality is what earns it a separate county record, even though the two entries describe what is, in the ground, a single feature.

Enclosures of this kind are among the most common, and most ambiguous, monuments in the Irish landscape. The term covers a wide range of circular or sub-circular earthworks, from early medieval farmsteads to prehistoric ceremonial sites, and without excavation it is rarely possible to say which a given example represents. What is known about this one comes largely from cartographic evidence: it appears on the Ordnance Survey six-inch map of 1841, which means surveyors could still make it out in the landscape at that time. Today it is no longer visible at ground level, meaning the earthwork has been levelled or eroded to the point where nothing rises above the surrounding terrain. The 1841 mapping therefore preserves a record of something that has since effectively disappeared from view.
