The Cathedral is located at the heart of the Força Vella. Built between the 11th and 18th centuries, it includes a series of walls and spaces in different styles, from Romanesque (the cloister and Charlemagne tower) to the baroque façade and steps. Its most singular feature is its large Gothic nave (15th-16th centuries) which, at a width of 23 metres, is the widest of its kind in the world.
