Sarrià - The city's most important "green lung". The proximity to Collserola and their unique natural setting, with springs and green spaces, made them a popular residential area for the moneyed classes in the second half of the 19th century. The most outstanding examples are the Casa Bellesguard and its viaduct, designed by Gaudí, and the mansions on the Avinguda del Tibidabo, with its famous century-old blue tram, the Tramvia Blau.
