Not that I am an expert on modernista arquitecture by any means but I had never heard of the Hospital San Pau, a complex of buildings designed by Domènech i Montaner. Beautiful tile is to be found covering floors, walls, ceilingand roofs. Practically every conceivable surface. Delightful. 10€ admission.
Inside looking out onto the hospital grounds. This would have been an inspirational place to be recovering from an illness.
