This Gothic building (14C-16C) highlights a variety of 16C architectural and sculptural styles. The fine works of art on show here include the high altar retable (early 16C) with its sculptures by Felipe Bigarny and paintings by Juan of Flanders. Behind the high altar, admire the exuberant Gothic Sagrario chapel. The central triptych (1505) is a masterpiece of Flemish art by Jan Joest de Calcar. To the side of the trascoro, a Plateresque stairway leads to the Romanesque crypt.
