Casa Batlló

Commissioned by the textile industrialist Josep Batlló, Gaudí transformed an ordinary block into one of the most expressive buildings on Passeig de Gràcia. The façade glitters with glass and ceramic fragments, the balconies resemble masks or bones, and the roof ridge is often read as the spine of a dragon.

The visit, which takes a little over an hour, runs through the main floor, the light well lined with graded blue tiles, the attic arches and the roof terrace, with digital installations along the way. The house opens daily until late, so an evening slot is a good way to avoid the midday crush. Combine it with La Pedrera a few blocks up the same avenue.
