the north door (portada norte), initially of romanesque design, has a variety of gothic additions. the tympanum is crowned by a cross where mary takes possession of christ's body. other decorations include an allusion to the miracle of st martin who is depicted tearing his cloak in two as well as the figure of james the apostle (known as santiago in spanish). the turrets on either side of the entrance are no doubt the result of the need to protect the doorway which had been destroyed by rodrigo alonso pimentel in 1471.
