With your prepaid admission voucher in hand, arrive at Sant Pau, located on Sant Antoni Maria Claret in central Barcelona. Buying your ticket ahead of time guarantees you admission to one of Barcelona's popular attractions. 

Begin your self-guided tour at the Administration Pavilion anytime during the facility's opening hours. Wander around the exhibition space, where you can learn about the facility's contribution to medicine and its artistic heritage through an interactive touch table and a video presentation. Explore the network of underground tunnels, which wind their way to the building's collection of pavilions and out into the gardens. Check out the architectural details of the building's exterior, such as stained glass, sculptures, and domes. 

Head to the restored Sant Rafael Pavilion and the old Surgery Room, then to the Lluís Domènech i Montaner Room, the Pau Gil Room, and the Main Hall. End up at the Sant Jordi Pavilion, host to the series of rotating temporary exhibitions.
