The two arms of the transept consist of two sections arched in the same way. The crossing is the only section that features complex ribbing, incorporating tiercerons between the main veins. From the crossing to the head, the naves are extended with three sections. In this posterior space, the four aisles, two on each side, balance the width of the transept, resulting in two separate areas of equal height and divided into six sections separated by four pillars. The slender bell tower, located on the portico of the entrance, is clearly inspired by the spires of the Cologne Cathedral. The set of pilasters and buttresses terminating in pinnacles and spirelets decorated with buds enhance the verticality of the building.
