Pendragon Castle is reputed to have been founded by Uther Pendragon, the father of King Arthur. According to legend, Uther Pendragon and a hundred of his men were killed here when the Saxon invaders poisoned the well. There are also claims that the Romans built at least a temporary fort here, along the road between their forts at Brough and Bainbridge. But (apart from legend and supposition), there is no real evidence that there was any building here before the Normans built their castle in the 12th Century.
