Inaugurated in 1908, after three years of building work orchestrated by the famous architect Lluís Domènech i Montaner, it is one of the most characteristic modernist buildings in the city. It is also one of the world’s major concert halls and an excellent example of Catalonian Modernism. The interior is decorated with ceramic mosaics and polychrome glass with floral motifs. In 1997 it was declared a World Heritage site by UNESCO.
