The rectangular enclosure, measuring approximately 52 metres east to west and 45 metres north to south, first appeared on the 1839 Ordnance Survey map, though its origins likely date back several centuries earlier. Today, the grass-covered central area spans roughly 32 by 30 metres, surrounded by the remnants of defensive earthworks that once protected whatever structures stood within.

The site’s perimeter tells its own story through varying states of preservation. Along the eastern and southern boundaries, old field banks and hedgerows now define the edges, having long since replaced any original fortifications. The western and northern sides, however, retain more dramatic evidence of the site’s defensive past; here, portions of the original moat survive, ranging from 11 to 13 metres in width and still reaching depths of around 0.8 metres. The northern section is particularly well preserved, complete with a counterscarp bank, an outer defensive earthwork that would have made any assault on the enclosure significantly more difficult.

These moated sites are characteristic of Anglo-Norman settlement patterns in medieval Ireland, typically dating from the 13th to 15th centuries. They served as fortified homesteads for colonists and local lords, combining residential, agricultural, and defensive functions. The Corbally site, recorded in Barry’s 1977 survey and later included in the Archaeological Inventory of County Wexford, stands as one of many such earthworks scattered across the Irish countryside, each one a monument to the complex layers of settlement, conflict, and adaptation that shaped medieval Ireland.
