From the transept, on each side of the choir, two large late-Gothic chapels, added in the 16th century (for the northern Chapel of the Blessed Sacrament of the Miracle), and the 17th century (for the southern Chapel of Our Lady of Deliverance), protrude. The large proportion of these chapels gives the impression that the building has three choirs. Behind the apse, on the central axis of the church, the Chapel of St. Mary Magdalen (also called the Maes Chapel), in Baroque style, was inserted in 1672–75 between the buttresses, with an octagonal plan with dome and lantern.
