Though no visible traces of the castle remain today, the circular earthwork that once supported it still dominates the landscape. The mound itself, measuring approximately 30 metres across at its summit and rising 3.5 metres high, presents something of a mystery; it may have been an Anglo-Norman motte, purpose-built as a defensive position, or perhaps a natural hillock that was artificially scarped and flattened to create a suitable platform for castle construction. Evidence of a defensive fosse, or ditch, can still be traced around the northern base of the mound, though modern farm development has obscured much of the original earthwork’s southern and western sides.

The castle’s complete disappearance isn’t unusual for such sites, and some archaeologists suggest the mound itself may partially consist of collapsed debris from the original structure. Historical maps tell a story of gradual encroachment and damage; the 1838 Ordnance Survey shows the mound intact as a circular platform, whilst by 1908, buildings had been cut into its southern side and further damage appeared on the western face. A lime kiln, marked on the earlier map just northeast of the mound, hints at one possible fate for the castle’s stones, though more likely they found their way into nearby Rathdrum House, built immediately southwest of the castle site.

One intriguing remnant may survive in the fabric of Rathdrum House itself: a crude stone head incorporated above a doorway. First recorded in 1942, this oval carving shows only basic facial features, and whilst its workmanship suggests an 18th-century date, it may originally have adorned the lost castle. Despite various archaeological surveys since the 1940s, including detailed examinations in 1977, no wall footings, dressed stones, or other structural evidence have been found on the mound’s summit. Today, the site serves as grazing land, with modern farm buildings and a silage pit having claimed portions of what was once a significant medieval fortification.
