Casa Batlló

Gaudí was hired in 1904 to remodel an ordinary 1870s apartment block, and by 1906 he had changed almost everything. The façade glitters with glass and ceramic discs, and the balconies look like masks. Locals still call it the House of Bones.

Inside, the Noble Floor flows in curves, with a mushroom-shaped fireplace nook and oak doors shaped to the hand. The light well is tiled in blues that deepen towards the top, so daylight spreads evenly down every floor. On the roof, the arched ridge is covered in scale-like tiles, often read as the dragon slain by Sant Jordi.
