Sorhaut

Soran, Sorant, Sorehaut, Sorham, Sorhan, Sorhaute, Sourchault, Sourehault

Malory mentions this British city as:

a city that hight Sorhaute, the which city was within King Uriens' [land].

This would put it in Gore.

In the Vulgate Lancelot, it is a city belonging to Galehaut (Galeholt) and Urien in the Vulgate Merlin. In the latter it was the capital of Gorre, and it served as a base of operation for the northern kings in their battles against the Saxons. Lancelot names it as the chief city of Sorelois.
