🏰 Rhayader Castle

Rhayader Castle is the remains of a motte-and-bailey castle in the town of Rhayader, Powys, Wales. The available documentary sources are not clear enough to distinguish between this site and the castle mound across the river and one or the other was probably built by Rhys ap Gruffydd, Prince of Deheubarth, in 1177. At that time the river formed the border between Gwrtheyrnion and the independent state of Buellt; the town of Rhayader is on the Gwrtheyrnion side of the river.
