An oval enclosure, roughly fifty metres across in both directions, shows up as a cropmark on aerial photographs, its outline preserved not in stone or earthwork but in the differential growth of grass and crops over buried features beneath. It is the kind of site that would be entirely invisible to someone walking past it, yet becomes unmistakable when viewed from above.

Cropmarks form when buried walls, ditches, or pits affect how deeply plant roots can reach into the soil, causing subtle variations in colour and growth rate that become visible from altitude, particularly during dry summers when the contrast is most pronounced. The enclosure at Skehanagh, in the barony of Pubblebrien, was identified through Digital Globe orthophotos taken between 2011 and 2013, and through Ordnance Survey Ireland aerial photography from roughly the same period. The site sits on a slightly undulating, east-facing slope in pasture, with moderate to good views in most directions, which is broadly consistent with the kind of position that enclosed settlements of the early medieval period often occupy in the Irish landscape. Approximately forty metres to the north lies a second, levelled enclosure, recorded separately in the national monument record, suggesting this part of Skehanagh may have seen a degree of activity across some span of time, though the notes do not venture a date or function for either site.

Because the enclosure survives only as a cropmark, there is nothing to see on the ground in the conventional sense. The pasture field shows no obvious surface trace. For anyone with an interest in landscape archaeology, the value here lies less in visiting the spot than in understanding how much of Ireland's past remains embedded just beneath ordinary farmland, unnoticed until the right conditions and the right camera happen to coincide. The site was compiled in the national record by Caimin O'Brien and uploaded in August 2020, part of an ongoing effort to document features that might otherwise be lost entirely before they are ever formally examined.
