First spotted on vertical aerial photographs from the 1950s, this 37-metre by 35-metre wooded area conceals the remains of a medieval moated site, a type of defended settlement that was once common across the Irish countryside.

The site is defined by substantial earthen banks that rise between half a metre and a metre on the interior side, whilst the exterior banks reach impressive heights of up to 2.8 metres. These defensive earthworks are accompanied by flat-bottomed ditches or moats on three sides; their bases measure two to three metres wide and drop to depths of 1.2 to 1.6 metres below the surrounding ground level. The western side tells a different story, where a north-south stream provides a natural water barrier, eliminating the need for an artificial moat. Even today, water still fills the northern section of the moat, offering a glimpse of how this defensive feature would have functioned centuries ago.

Moated sites like this one at Gallagh were typically built during the Anglo-Norman period, serving as fortified farmsteads for colonising families or as administrative centres for managing agricultural estates. The combination of earthen banks and water-filled moats provided both practical defence and a clear statement of status in the medieval landscape. This particular example, documented in the Archaeological Inventory of County Wexford and updated through recent research, represents one of many such sites scattered across the county, each telling its own story of medieval settlement and land management in Ireland.
