Modernist design by Lluís Domènech i Montaner is a UNESCO World Heritage site, a masterpiece of Catalan's modernist architecture. This auditorium designed by Ramon Muntaner is the most important Modernist example in Ciutat Vella. It was the headquarters of the Orfe Catal , the oldest Catalan choir. The most beautiful part is the stalls with its fine detailing, although all the building is impressive. There are plenty of allegories about music and Catalonia, since the Orfe Catal is strongly bounded with the Catalan Renaixen a, the romantic movement that tried to recuperate the Catalan history, language and traditions. It is also the best place in Barcelona to listen to symphonic music.

Palau de la Música Catalana (Catalan pronunciation: [pəˈlaw ðə lə ˈmuzikə kətəˈlanə], English: Palace of Catalan Music) 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 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 on 9 February 1908.

The construction project was mainly financed by Orfeó Català, but important financial contributions also came from Barcelona's wealthy industrialists and bourgeoisie. The palace 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 palace 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 (Catalan song).
