This Gothic building (14C-16C) presents a variety of 16C architectural and sculptural styles. Some fine works of art are on show here include its high altar reredos (early 16C) which intersperses sculpture by BFelipe Bigarny and pictures by Jean de Flandre. Behind the high altar is the exuberantly Gothic Sagrario Chapel. The central triptych (1505) is a masterpiece of Felmish art by Jan Joest de Calcar. To the side of the trascoro, a stairway leads to the Romanesque crypt.
