A city in southwest England, on the Severn river.

In Ambrosius’s time, according to Geoffrey of Monmouth, it was ruled by Earl Eldol, and the bishop was his brother Eldad; later, the Earl of Gloucester was Morvid.

In the Vulgate Merlin, an unnamed Earl of Gloucester fights in Arthur’s army in the Roman War. In Culhwch and Olwen, Arthur’s warriors rescue the huntsman Mabon from a Gloucester prison. The English ballad "King Arthur’s Death" names Arthur’s Sir Lucan as Gloucester’s duke.
