The only reason it is known to exist at all is a set of aerial photographs taken in 1973, in which the outline of a circular enclosure shows up as a cropmark, the kind of ghost-image that appears when buried foundations or ditches cause the vegetation above them to grow differently, often more vigorously or more sparsely depending on soil moisture and depth. Without that particular angle of light, that particular season, and that particular flight, the site might have gone entirely unrecorded.

Cropmark enclosures of this kind are frequently associated with prehistoric or early medieval activity in Ireland, where circular forms in the landscape can indicate anything from a ringfort, a type of enclosed farmstead used roughly between 500 and 1000 AD, to much earlier Bronze Age or Iron Age enclosures. The Wicklow landscape holds many such buried features, and level marshy ground of this sort tends to preserve organic and structural material well, even as it makes the surface above utterly unremarkable. The GSI aerial survey from which this site was identified captured a significant number of similar features across the country during the early 1970s, adding quietly to the record of what lies beneath ordinary-looking farmland.
