A city in the county of Avon, southwest England.

According to Geoffrey of Monmouth, it was founded by King Bladud in the tenth century BC. Bath was besieged by Saxons in Arthur's reign, but Arthur arrived in time to save the city and kill the Saxon leaders Colgrim (Colgrin) and Baldulph (Baldulf). Later, Urbgennius served as the Earl of Bath.

Geoffrey's use of Bath as the scene of this decisive battle indicates that he believed Bath to be the location of Badon.

Chrétien names this as one of King Bademagu's court cities, which affects the geographical placement of the land of Gore.
