FitzHarris Castle

FitzHarris Castle stands in Oxfordshire near the town of Abingdon. It was built between 1071 and 1084 by a Norman knight named Owen soon after the Norman invasion. The castle occupied a small mound measuring 78 by 68 feet, surrounded by a stream that formed a defensive moat. A keep stood on the mound as late as 1247, though the nearby manor house called FitzHarry’s later overshadowed its military role. Today the site belongs to the local authority and is recognised as a scheduled monument. The castle’s remains are modest but historically significant. English Heritage lists it as at risk from erosion caused by visitor numbers, which shows how fragile such sites can be. Its construction reflects the rapid Norman consolidation of power after 1066. The motte-and-moat design was typical of early Norman fortifications in England. Owen’s choice of location near Abingdon placed it close to a growing settlement and trade routes. A visitor finds a low, grassy mound with no standing walls, just the faint outline of the moat. The site lies in a quiet field on the edge of modern Abingdon. There are no buildings left above ground, only the earthworks that once supported the keep. The stream that once filled the moat still flows nearby, though it no longer encircles the mound. The open space around the mound lets the shape of the original castle be imagined.
