The rectangular wooded enclosure measures 41 metres from east to west and 38 metres from north to south, with its perimeter clearly defined by earthen banks that rise at each corner. These banks are substantial features; on the western side, for example, they stretch 5 metres wide and stand 0.8 metres high on the interior, whilst reaching an impressive 2 metres in height when viewed from outside.

The site’s most striking feature is its external moat, which completely surrounds the central enclosure. This defensive ditch has a flat bottom and maintains consistent dimensions around the perimeter; at the western side, it spans 10 metres across at the top and plunges 2 metres deep. Beyond the moat lies yet another earthen bank, creating a second line of defence. This outer bank, measuring 4 metres wide and 0.6 metres high on the western side, runs along each side of the site. Curiously, archaeologists have been unable to identify any obvious entrance to the enclosure, leaving questions about how its medieval inhabitants accessed this well-fortified space.

First documented by Barry in 1977 and later included in the Archaeological Inventory of County Wexford published in 1996, this site represents one of many moated sites scattered across the Irish countryside. These earthwork fortifications typically date from the Anglo-Norman period and served as defended homesteads for colonists and local lords alike. The Ballymore example, with its well-preserved banks and moat system, provides valuable evidence of medieval settlement patterns and defensive strategies in south-eastern Ireland.
