SH 781-794 Caernarfonshire Wales
Deganwy Castle is an ancient Welsh royal site but sadly this substantial stone motte and bailey fortress, has been built and dismantled three times. The two natural mottes flank a middle lower bailey, which has the fragments of a mighty twin towered gatehouse that once flanked its southern curtain wall, with a small gatehouse guarding its northern banks and ditches. On the eastern motte are the foundations of Mansell's Tower, a great D-shaped keep and on the western motte are the fragments of a barbican, a low curtain wall, flanked by a solid round turret, a hall and a keep. One mile south is Conwy Castle.
