Barcelona is celebrated for its Catalan Modernism architecture, especially buildings designed by Gaudí. Yet Lluís Domènech i Montaner was masterful in his use of decorative shapes, colorful mosaics, open design, intricate statuary and elegant features. He was also a professor and director of the local architecture school for 45 years, so he influenced generations of designers. Montaner’s masterpiece is Palau de la Música Catalana, finished in 1908. The performances within the 2,200 seat concert hall are delightful. But the lasting triumph is the façade of the Palace of Catalan Music. Don’t miss savoring this UNESCO World Heritage Site.
