Palau de la Música Catalana (Barcelona/ Spain)

The Palace of Catalan Music is a concert hall designed in the Catalan modernista style by Lluís Domènech i Montaner.
It's the only auditorium in Europe that is illuminated during daylight hours entirely by natural light thanks to its stained-glass walls and enormous inverted dome skylight which was designed by Antoni Rigalt in shades of gold surrounded by blue that suggests the sun and the sky.
It was built between 1905 and 1908 and in 1997 it was declared a UNESCO World Heritage Site.
