The doors on the north façade run along Cardenal Herrero Street. From west to east, the following can be visited:
The Arca del Agua is a cistern from the 18th century that is attached to a cassette in the north wall. The cistern serves to protect and ventilate the main ark of the chapter house that distributes water to the other fountains and houses in the surrounding area. The ark is made of brick and is located on the platform of the Mosque. It has a square floor plan with pilasters at the corners and two sections with cornices, topped by a dome.
The Puerta del Perdón (Forgiveness Gate) is in the Mudéjar style and is located next to the tower. It was built in the 14th century and later reformed in the 17th century. It consists of two horseshoe arches, one facing the street and the other the courtyard of the Orange Trees, between which is a quadrangular space with a domed roof.88 On the spandrels of its outer arch is the coat of arms of King Henry II. Above it are three polybullous blind arches decorated with paintings by Antonio del Castillo.
The Caño Gordo Gate is neoclassical in style, built in the 16th century and renovated in the 18th century.89 It is named for its proximity to the Caño Gordo fountain.
The Caño Gordo Fountain is a fountain attached to the north wall. It was already known in the 10th century. Its present form is Baroque from the 18th century and has a buried basin made of a single piece of blue marble and a large-diameter brass spout on a simple square façade.
The altar of the Virgin of the Lanterns is located on the outside of the north wall. It features a Virgin of the Assumption protected by an exterior grille surrounded by 11 lanterns. The current Virgin, the work of the painter Julio Romero de Torres, is a copy of the original, which was transferred to the painter's museum in the city.
