The chevet, at the northeast end of the cathedral, close to the transept, has vestiges that go back to the Romanesque cathedral, particularly at the lower levels. It looks over the former cloister of the canons of the cathedral. It is the least decorated side of the cathedral. A large arched bay occupies the central portion, just below a balustrade. Above that are three narrow windows and then a triangular gable with a small circular oculus window and blind arches. The face is flanked by two cylindrical towers with narrow lancet windows and pointed roofs. The walls are pierced with narrow slits, like a medieval fortress, giving it a very military appearance.
