One of the strangest residential buildings in Europe, this is Gaudí at his hallucinatory best. The facade, sprinkled with bits of blue, mauve and green tiles and studded with wave-shaped window frames and balconies, rises to an uneven blue-tiled roof with a solitary tower.
It is one of the three houses on the block between Carrer del Consell de Cent and Carrer d’Aragó that gave it the playful name Illa de la Discòrdia (Spanish: Manzana de la Discordia), meaning ‘Apple (Block) of Discord’. The others are Puig i Cadafalch’s Casa Amatller and Domènech i Montaner’s Casa Lleó Morera. They were all renovated between 1898 and 1906 and show how eclectic a ‘style’ Modernisme was.
Locals know Casa Batlló variously as the casa dels ossos (house of bones) or casa del drac (house of the dragon). It’s easy enough to see why. The balconies look like the bony jaws of some strange beast and the roof represents Sant Jordi (St George) and the dragon. Even the roof was built to look like the shape of an animal’s back, with shiny scales – the 'spine' changes colour as you walk around. If you stare long enough at the building, it seems almost to be a living being. Before going inside, take a look at the pavement. Each paving piece carries stylised images of an octopus and a starfish, designs that Gaudí originally cooked up for Casa Batlló.
When Gaudí was commissioned to refashion this building, he went to town inside and out. The internal light wells shimmer with tiles of deep-sea blue. Gaudí eschewed the straight line, and so the staircase wafts you up to the 1st (main) floor, where the salon looks on to Passeig de Gràcia. Everything swirls: the ceiling is twisted into a vortex around its sunlike lamp; the doors, window and skylights are dreamy waves of wood and coloured glass. The same themes continue in the other rooms and covered terrace. The attic is characterised by Gaudí trademark hyperboloid arches. Twisting, tiled chimney pots add a surreal touch to the roof.
