Montjuïc Castle is an ancient military fortress dating back to 1640, located in the Montjuic area of Barcelona. The fortress is part of the long history of the city of Barcelona. Immediately after it was built, it was used during a deadly revolt when the Catalan nation fought against the Spanish ruler. Fifty years later, it was enlarged from a fortress to a castle. It was then dismantled and rebuilt, and took part in Napoleon’s wars.
