INNER WALL THE BISHOP'S TOWER  his tower, built at the end of the XIIIth Century, on the west facade in the narrowest part of the lists, is so named because of the proximity of the old Episcopal palace. The square structure rises above two lines of fortification where a vaulted passageway with cross-ribbed vaults ensured circulation in the lists. The flat buttresses that support these corners are topped with watch towers designed to defend the Aude Gate.
