11Palau de la Musica Catalana
A masterwork of Catalan art nouveau, the Palace of Catalan Music was constructed by an architect named Lluís Domènech i Montaner. Its noteworthy architectural features garnered the building official designation as a UNESCO World Heritage site. See the busts of such famous musicians as Beethoven and Bach and the rather intricate mosaic pillars.
This concert venue’s interior has a beautiful floral motif and stained glass windows. It also includes memorable sculptures and more mosaic pillars. Most notably, it also has a huge central stained glass skylight.
