The area’s medieval history traces back to the late 12th century when William Brun and his son Nicholas witnessed a charter granted by Hervey de Montmorency to Dunbrody Abbey between 1178 and 1182. The Brun family maintained their connection to these lands for generations; William held Mulrankin by half a knight’s fee in 1247, and Nicholas continued this tenure in 1307 as part of the Bigod estate.

By the late medieval period, the property had passed to the Browne family. Patrick Browne appears in records from 1381 concerning 160 acres at Ballycappoge and the now-lost townland of Drumfellin. This mysterious settlement, which Robert Brown owned at his death in 1634, seems to have vanished from maps by the mid-17th century, likely absorbed into the greater Ballycappoge area. The Civil Survey of 1654-6 notes that David Brown held both the castle and 180 acres here in 1640, though by then Drumfellin had already disappeared from official records.

Today, visitors won’t find much of the castle itself; its location appears only on the 1940 Ordnance Survey map, which places it within a moated site that likely served as the castle’s original footprint. Archaeological excavations conducted in 2006 about 100 metres southeast of the site yielded no related artefacts, leaving the exact nature and extent of the medieval fortification to the imagination. The moated enclosure remains the primary evidence of this once-significant Norman stronghold that watched over the Wexford countryside for centuries.
