Sarrià-Sant Gervasi is the fifth district of Barcelona. It has an area of 20.09 km2 and a population of 148,172 inhabitants. It is one of the greenest districts of the city and, together with Horta-Guinardó, the gateway to the Sierra de Collserola natural park, the most important lung of Barcelona.
This proximity marks its condition as a residential and affluent area, with numerous parks and green areas, combined with prestigious educational and health centers.
The district is the sum of former municipalities added to Barcelona, such as Sarrià (1921), Vallvidrera-Les Planes (annexed to Sarrià in 1890) and Sant Gervasi de Cassoles (1897). Sarrià maintains the unity of the old town, although this nucleus is separated from the Three Towers by its homogeneous urban characteristics and the high degree of recognition it has by its inhabitants.
Sarrià-Sant Gervasi is a village-like nucleus, composed of the neighborhoods of Sarrià, Las Tres Torres, Sant Gervasi-la Bonanova, Sant Gervasi-Galvany, Vallvidrera, Tibidabo i les Planes and Putxet i el Farró.
