Barcelona is a city that is characterized by its architecture and beauty, since 1984 UNESCO has declared 9 architectural works as world heritage, seven of them by the architect Antoni Gaudí, along with 2 buildings by Lluís Domènech I Montaner.

The first buildings in the Catalan capital that entered the UNESCO list were Park Güell and La Pedrera, both by the architect Antoni Gaudí. The next to enter the list was also the work of Gaudí, the Palau Güell, built in 1889 on behalf of Gaudi’s great patron, Eusebi Güell.

The two great architectural works of the architect Lluís Domènech I Montaner, the Palau de la Música Catalana (1908) and the Hospital de la Santa Creu I de Sant Pau (1930) were declared World Heritage Sites in 1997 and are the only buildings in Barcelona with this classification that are not the work of Gaudí.

The list is closed by the Sagrada Familia, Casa Batlló, the Crypt Colònia Güell and Casa Vicens, which were declared World Heritage in 2005.
