Ambrosius Aurelianus
Geoffrey of Monmouth wrote about the town, claiming that it had been fortified by Ambrosius Aurelianus, King of the Britons after his victory over the Anglo-Saxon forces of Hengist (Historia Regum Britanniae viii, 7), that the captive Anglo-Saxon leader Hengist was hacked to pieces by Eldol outside the town walls, and was buried at "Hengist's Mound" in the town.
