Cardona Castle

This is the last bit of the Principality that succumbed to the Bourbons in 1714. A refuge for the viscounts, earls, and dukes of Cardona for seven centuries, kings uncrowned by the 'white gold' (salt), it's an imposing place with two great treasures: the divine Romanesque collegiate church of Sant Vicenç and the Minyona tower. A Gothic cloister was added, and 17th-century bulwarks. The castle also boasts a, recently made into a museum, all of which makes up the monument that is the History Museum of Catalonia, with all that entails.
