Deganwy Castle is a medieval fortification situated on the Conwy Peninsula in north Wales, commanding views over the Conwy Estuary and Deganwy village. The castle consists of the fragmentary remains of stone towers and walls, representing the work of multiple building phases from the thirteenth century onwards. Originally established as a Welsh stronghold, the site was captured and rebuilt by Edward I's forces during the conquest of Gwynedd in the late thirteenth century, after which it served as an English garrison castle. The visible remains today include substantial portions of masonry from the medieval period, though erosion and later quarrying have significantly compromised the structure, leaving it as a prominent archaeological monument recording an important phase of medieval military architecture and Welsh-English conflict.
