The legendary Casa Batlló
If you walk along the Passeig de Gràcia boulevard you can’t miss it: the colourful façade of Casa Batlló. The building’s frontage invites closer inspection. With its playful round windows and scaly roof, it has the aura of a fairytale castle. Its shapes and lines immediately reveal the identity of its creator: Antoni Gaudí, Barcelona’s most celebrated modernistic architect.
