Ganarew

Generth, Generon, Genoreu

A castle on Mount Doward in the country of Archenfield in Wales. The castle sat along the River Wye.

According to Geoffrey of Monmouth, King Vortigern fled to this castle when pursued by Ambrosius Aurelius and Uther, who had come from Brittany to conquer the land. Vortigern fortified himself, but Ambrosius simply set the castle on fire and burned Vortigern alive.

Nennius calls the same castle Vortigern.
