A rectangular enclosure, roughly 38 metres east to west and 35 metres north to south, shows up not as a standing structure or a visible earthwork but as a cropmark, the kind of ghostly outline that appears in aerial or satellite photography when buried ditches or drains cause the vegetation above them to grow differently from the surrounding soil. The enclosure sits on a slight east-west ridge, and it is defined by what appear to be single fosses, a foss being a ditch or trench, often used to demarcate an enclosed area in early medieval or prehistoric settlement.

The site was first reported by Jean Charles Caillére, and it appears in Ordnance Survey Ireland imagery from 1995, meaning the outline has been quietly present in the record for decades. It became more clearly visible in a Google Earth satellite image captured on 21 July 2021, which allowed the cropmark to be traced with greater precision. Cropmark sites like this one are sometimes all that survives of enclosures that once had a practical function, whether as farmsteads, cattle pounds, or more ceremonially bounded spaces. Without excavation, the date and purpose of this particular enclosure remain open questions.

There is nothing to see at ground level, which is part of what makes it interesting. The enclosure exists, at least to any observer, only as data, a pattern pressed into the landscape and retrievable through the right kind of looking. County Louth, one of Ireland's smallest counties, has a surprisingly dense archaeology, and sites like this one serve as a reminder that the visible and the surviving are rarely the same thing.
