This magnificent cathedral dates from 1158 but was rebuilt in the 15th to 16th centuries. It reopened in 2011 after 30 years of restoration work. Elements from its French-Gothic roots can be observed in the frescoes in the high altar, Mudéjar influences can be seen in the intricate masonry, Renaissance artwork is reflected in the decorative chancel and carved altars, while the main portal and retrochoir display paintings from the baroque era.
The adjoining cloister acts as a small museum focusing mainly on the meticulous restoration work. An audio-guide cost €1.50.
