An eye-catching fixture of downtown Barcelona, the Palau de la Música Catalana boasts a striking modernist design. It was built in the early-20th century by architect Lluís Domènech i Montaner, who designed the now-iconic exterior to feature intricate carvings, red brick arches, and exquisite Spanish and Arabic architectural details. Inside, the concert hall is even more breathtaking with its gold accents, floral patterns, and exceptional stained-glass elements. Visitors to the Palau de la Música Catalana will be awed by the kaleidoscopic skylight whether they take in a show or simply tour this breathtaking UNESCO World Heritage Site. In the past, the Palau de la Música Catalana has hosted such quality performers as Ella Fitzgerald, Paco de Lucía, Woody Allen, Ángel Corella, and Duke Ellington.
