In the heart of the Sant Pere neighborhood, among the narrow historic streets of Barcelona, stands the Palau de la Música Catalana, a masterpiece of Catalan modernism designed by Lluís Domènech i Montaner between 1905 and 1908 to house the Orfeó Català choir. It is the only concert hall in the world declared a UNESCO World Heritage Site, recognized for its architectural and cultural value.

The exterior facade is an explosion of color and decoration, composed of red bricks, floral mosaics, glazed ceramics, and allegorical sculptures like La Cançó Popular Catalana by Miquel Blay. Inside, the renowned Auditorium can accommodate up to 2,200 spectators: an incredible space adorned with stained glass windows, mosaics, columns depicting musicians, busts of composers such as Bach, Beethoven, and Wagner, and a central skylight that illuminates the hall with natural light.

During the guided tour (approximately 50 minutes), visitors can access the choir's Rehearsal Hall, the Lluís Millet Room with polychrome glass, the grand staircase adorned with mosaics, and the panoramic terrace. In some cases, visitors can attend a mini organ concert or observe rehearsals from the stage.

The Palau continues to host concerts of classical music, jazz, Catalan songs, and contemporary performances in its musical spaces. The tour is available in different languages, with audio guides and thematic visits such as the "Essència Palau" experience, which combines scents, history, and poetry inspired by the flowers of the modernist décor.
