The Palau de la Música Catalana is a concert hall in Barcelona, Catalonia, Spain. Designed in the Catalan modernista style by the architect Lluís Domènech i Montaner, it was built between 1905 and 1908 for the Orfeó Català, a choral society founded in 1891 that was a leading force in the Catalan cultural movement that came to be known as the Renaixença (Catalan Rebirth). It was inaugurated February 9, 1908. The project was financed primarily by the society, but important financial contributions also were made by Barcelona's wealthy industrialists and bourgeoisie. The Palau won the architect an award from the Barcelona City Council in 1909, given to the best building built during the previous year. Between 1982 and 1989, the building underwent extensive restoration, remodeling, and extension under the direction of architects Oscar Tusquets and Carles Díaz. In 1997, the Palau de la Música Catalana was declared a UNESCO World Heritage Site along with Hospital de Sant Pau. Today, more than half a million people a year attend musical performances in the Palau that range from symphonic and chamber music to jazz and Cançó The design of the Palau is typical of Catalan modernism in that curves predominate over straight lines, dynamic shapes are preferred over static forms, and rich decoration that emphasizes floral and other organic motifs is used extensively. In contrast to many other buildings built in the modernisme style, however, it must also be said that the design of the Palau is eminently rational. It pays strict attention to function and makes full use of the most up-to-date materials and technologies available at the beginning of the 20th century (e.g., steel framing). As Benton (1986, 58) has pointed out, "To eyes unaccustomed to the architecture of Barcelona, the impression of a riot of ornament lacking any logic or control seems overwhelming. And yet the building follows exactly the exhortations of the [architectural] rationalists. The structure, in brick and iron, is clearly expressed." Actually, its walls are the first example of curtain wall structures.
