The site, situated on a shelf along a south-facing slope in what locals still call “the lawn”, consists of an oval depression measuring roughly 23 metres east to west and 16 metres north to south. Early Ordnance Survey maps from 1839 show a faint rectangular structure here, approximately 10 metres by 5 metres, though by 1924 only the notation “site of castle” remained on official cartography.

The Sutton family’s presence at Oldcourt was marked by both prosperity and peril. David Sutton, who likely had connections to the Suttons of nearby Ballykeeroge, found himself victim to the extortion of Art Boy MacArt Kavanagh in 1580, a reminder of the lawlessness that plagued 16th-century Ireland. Despite such setbacks, by the time of the Civil Survey conducted between 1654 and 1656, Sutton had amassed considerable holdings; 120 acres, the castle itself, and according to Transplantation documents from the same period, 39 people were associated with his estate along with substantial property. The dwelling marked on the Down Survey barony map of 1655-6 almost certainly represents this very castle.

Archaeological testing carried out in 2003 about 60 metres northeast of the castle site yielded no related materials, suggesting that whatever remains of the structure lie undisturbed beneath the peaceful hollow. Today, visitors to this unremarkable field might easily pass by without realising they stand where one of Wexford’s 17th-century landowners once held court, a testament to how thoroughly time and nature can reclaim even the most substantial of human constructions.
