The old minaret of the Arab mosque. The bell tower, the diminishing niches and the El Giraldillo weather vane were added in the 16th century. The part decorated with bricks is the work of the architect Alí de Gómara. A series of ramps takes visitors up to the bell tower, which offers outstanding views over the city. The Orange Tree Courtyard, in the Almohad style with a Visigoth pool, is to one side.
