It measures 47 metres on its longer axis and 25 metres across, with rounded corners and a defining scarp, the step-like earthen edge that marks the outer boundary, rising to nearly one and a half metres on its south-east side. What makes it odd is its shape. Enclosures of this general type are common enough in the Irish landscape, but this one is unusually elongated, stretched out in a way that prompts the question of whether it was always this form, or whether something else came first.

The most likely candidate for that original structure is a rath, the term for a roughly circular or oval earthen enclosure, usually interpreted as a defended farmstead from the early medieval period. The proportions here suggest the rath may have been extended or substantially modified at some point, though no documentary evidence survives to say when or by whom. The structure does not appear on the 1838 Ordnance Survey six-inch map at all, which is notable given how systematically that survey recorded earthworks across the country. By the 1916 edition, it had been mapped as a subrectangular hachured enclosure, partially absorbed into a field boundary along its north-western edge. That boundary has since been removed. The scarp on the south-east side shows clear signs of past interference, its face slightly concave in plan, suggesting it was deliberately cut into at some stage. On the north-west side, the bank has been partly levelled to little more than a low rise. A few large stones protrude through the grass on the southern scarps, though some of these may simply be the result of field clearance rather than original construction.

About 45 metres to the south lies a souterrain, an underground stone-lined passage of the kind typically associated with early medieval settlement sites, often used for storage or refuge. Its proximity to the enclosure is unlikely to be coincidental, and the pairing of the two features gives the site a layered quality that the featureless grassy interior does little to advertise. The slope falls steeply away to the south, opening onto wide views across pasture and bog, the kind of position that would have made practical sense to anyone choosing where to settle or farm a thousand or more years ago.
