Montjuïc Castle, originally built as a military fortress in the 18th century, has transformed into a heritage site that offers cultural exhibitions and stunning views of Barcelona. This visit aims to highlight the evolution of the castle from an empty historic monument to a vibrant public space with intrinsic architectural and historical significance. Instead of focusing on external collections, the castle showcases its inherent values. The tour will cover key features, including barracks, dungeons, and reception areas that have been revitalized for cultural purposes. Participants will gain unique insight into the transformation process of a historically significant monument into a community resource while exploring areas that are usually restricted or under renovation, all while maintaining respect for the site's heritage and symbolic values.
