Known as the Dame of Cathedrals due to its size and elegance, this Gothic-style cathedral with Renaissance elements was built between the 16th and 17th centuries. It was intended as a substitute for the old cathedral, which was situated the vicinity of the Alcázar and destroyed in the Revolt of the Comuneros.
It's worth seeing mostly from the outside, and we recommend walking all way the around it. It is especially beautiful at night, when it is all lit up. If you'd like to go inside (unnecessary since, apart from the cloister, it has nothing to differentiate it from other cathedrals), you'll have to pay a 4€ entrance fee (Open 9:30 to 18:30 April to September and 9:30 to 17:30 October to March. Sundays free from 9:30 to 13:15).
