Biblioteca Sant Pau

Up until 1929, this Historic and Artistic Landmark of National Interest served as the main hospital of Barcelona. Now it is a library and cultural centre, with the courtyard space hosting markets, art fairs, and other events. The interior is also home to charming café that has live music in the evenings. If you’re a history buff and appreciate looking at old architecture, then be sure to check it out. However be respectful, as it’s functioning library still used by locals to this day.
