Crickhowell Castle is a Grade I listed medieval fortress positioned on a spur overlooking the River Usk in the town of Crickhowell, Wales, within the Brecon Beacons National Park. Originally constructed as a motte-and-bailey fortification by Anglo-Norman Marcher Lord Bernard de Neufmarche in the late 11th or early 12th century, the castle was refortified in stone from 1242 with substantial towers and a walled bailey. Though largely ruined following its destruction in 1403 by rebels under Owain Glyndŵr, the castle remains accessible to visitors year-round and represents a pivotal point of Norman control over central Wales's vital trade routes.
