The Palau de la Música Catalana is considered one of the foremost concert halls worldwide. Its designer was Lluís Domènech i Montaner, who constructed this building between 1905 and 1908. The architect took the greatest care with every detail, melding the constructive forms of the façade, the sculpture groups and the decorative forms of the concert hall in an ensemble charged with imagination and symbolism. The interior is especially attractive the natural lighting obtained through the splendid glazed dome. UNESCO declared the Palau de la Música Catalana a World Heritage Site in 1997.
