Though no longer visible at ground level, archaeological surveys from 1980 documented what was once a substantial defensive earthwork. The site occupies relatively flat, low ground with a stream running east to west approximately 30 metres to the south, a typical location choice for these medieval settlements which needed both defence and access to water.

The moated site originally consisted of a roughly rectangular area surrounded by impressive earthen banks, each about 5 metres wide and rising to 1.5 metres in height on the interior. These banks were fronted by flat-bottomed moats on all sides, measuring 2 metres wide at their base and 2 metres deep; formidable obstacles for any would-be intruder. Archaeological evidence also suggests traces of an additional outer bank to the south and southwest, indicating the site may have had multiple defensive layers. The main entrance was positioned at the northwest corner, a strategic placement that would have allowed defenders to monitor approaching visitors.

Such moated sites were commonly built in Ireland during the Anglo-Norman period, typically dating from the 13th to the 14th centuries. They served as fortified farmsteads for colonising settlers, combining residential, agricultural, and defensive functions within a single complex. While Scullaboge’s earthworks have since been levelled by centuries of farming and now exist only as buried archaeological features beneath the pasture, they represent an important chapter in Wexford’s medieval landscape, when new communities were establishing themselves across the Irish countryside.
