Aerial photography captured in 1989 shows the distinctive rectangular enclosure, its boundaries marked by what would have been a broad, water-filled ditch or fosse. Two entrance causeways can be seen on opposite sides, one facing southeast and the other northwest, providing access across the defensive moat to the settlement within.

The site’s layout suggests this was more than just a simple fortified homestead. A rectangular annexe extends from the western side of the main enclosure, and within it, the circular mark of another structure is clearly visible in the aerial photograph. This additional space might have served as a livestock enclosure, storage area, or perhaps housed additional buildings for an extended household or workers.

These moated sites are scattered across the Irish countryside, particularly in Leinster, and date primarily from the 13th and 14th centuries. They represent the homes of Anglo-Norman colonists and prosperous farmers who needed both to display their status and protect their holdings in what was often contested territory. Though nothing remains visible at ground level today, the cropmarks at Ballynasculloge preserve the footprint of this medieval settlement, its ditches and banks still affecting crop growth patterns hundreds of years after the last inhabitants departed.
