The audio guide of the Sagrada Familia innovates with two routes: the towers of the Passion Façade and the Nativity Façade. Visitors who take this tour, upon reaching the bridges that connect the towers, can enjoy views of the city, learn about the bell towers and spiral staircases, and discover the architecture. To complete the experience, a video is included to explain the aspects to be taken into account before starting the circuit. The tours are available in 19 languages, produced by Audioguiarte.
