Colwyn Castle
Colwyn Castle, also historically known as Maud's Castle, is a large and complex earthwork site located near Hundred House and Builth Wells in the community of Glascwm. The surviving remains represent one of the most significant early medieval fortifications in mid Wales. The castle occupies the site of a former Roman fort, and much of its scale and unusual layout derives from the reuse of those earlier defences. The earthworks cover close to ten acres, making Colwyn one of the largest medieval sites in Radnorshire. The most recognisable feature is a low motte, now partly occupied by modern buildings at Fforest Farm. Although reduced, the mound still forms a distinct rise above the surrounding landscape. Around the motte lies a large outer bailey, formed by substantial banks and ditches that incorporate the earlier Roman ramparts. The outlines of the Roman fort, including its rectangular plan and defensive earthworks, remain clearly visible within and around the medieval enclosures. The adaptation of a Roman fort for medieval use is rare in Wales. At Colwyn the Norman builders utilised the strong, pre existing banks and ditches, strengthening them and adding new defensive lines. This created a hybrid defensive system with both Roman and medieval elements preserved in the modern landscape. The earthworks remain sharply defined across large sections of the site, despite later agricultural use and the development of the farm. Colwyn Castle was first fortified as a Norman timber motte-and-bailey in 1093, probably by Ralph Tosny of Clifford, as part of the Norman advance into what later became Radnorshire. Its position at the edge of Maelienydd made it a strategic frontier post during the long struggle between Norman lords and Welsh princes. The castle changed hands repeatedly. It was captured and destroyed in 1196 by Rhys ap Gruffydd, the powerful ruler of Deheubarth, during his campaigns across the central borderlands. The site was later rebuilt several times, reflecting its ongoing value in controlling the Maelienydd region. Around 1240, the castle was reconstructed in stone by Ralph de Mortimer after he secured the lordship of Maelienydd. This rebuilding phase strengthened the fortification and reaffirmed Mortimer authority in the area. Despite these efforts, the castle gradually declined during the fourteenth century as political and military priorities shifted. By 1629 the site had been largely demolished, although its earthworks remained clearly visible. Today Colwyn Castle survives as a scheduled monument. The integration of Roman and medieval earthworks makes it an exceptional archaeological landscape and a key site for understanding early medieval lordship in central Wales. Alternate names: Maud's Castle, Castell Colwyn, Colwyn Motte and Bailey
