The enclosure that exists here survives only as a cropmark, a ghostly outline that becomes legible not to the walking visitor but to someone looking down from an aircraft. When crops grow unevenly over buried ditches, the differential moisture in the soil produces strips and patches of varying colour and height, and from above these resolve into shapes that are otherwise completely invisible at ground level. At Scart, that shape is a rectangle, roughly 60 metres from north to south and 40 metres from east to west, defined by the filled-in remains of a fosse, which is simply the technical term for a defensive or boundary ditch cut around an enclosure.

The evidence comes from an aerial photograph taken in July 1989 as part of the Cork Archaeological Survey Aerial Photography programme. The image reveals the cropmark of the fosse along the western, northern, and part of the eastern sides of the enclosure, with a second, outer fosse also traceable along the western and northern edges, suggesting the site was once bounded by at least two concentric ditches. The southeastern quadrant of the enclosure is harder to read, where disturbance to the crop disrupted the mark before it could be fully recorded. Immediately to the west lies a field system, a separate but possibly related arrangement of ancient boundaries and plots. Together they suggest this corner of north Cork was once an organised and perhaps significant piece of landscape, though without excavation the period and function of the enclosure remain open questions.
