A fortress in Britain that was the site of Arthur’s eighth battle against the Saxons. In this battle, we are told, Arthur
carried the image of the holy Mary, the everlasting Virgin, on his shield, and the heathen were put to flight on that day, and there was a great slaughter upon them.
Possible locations include castles in Cornwall, Winchester, and fortress of Garionenum in Norfolk.
Geoffrey and the Annales Cambriae adopt the image of Arthur’s shield from this battle for the battle of Badon.
