The colour and fantasy of the Casa Batlló captivates passers-by on the Passeig de Gràcia. Standing halfway up this elegant boulevard and in a strongly contrasting style to the neighbouring houses, the Casa Amatller and Casa Lleó Morera, this building reveals the splendour of an architect who was able to work on this project with total creative freedom, Antoni Gaudí.

The architect Antoni Gaudí undertook a radical refurbishment of a building in Barcelona's Passeig de Gràcia dating from 1875 to create one of his boldest works. Gaudí's imaginative efforts were key to the development of the project, as was the decorative work of the artisans who collaborated with him between 1904 and 1906. A simple glance gives rise to myriad interpretations. The discs of multicoloured glazed-ceramics and broken shards of stained glass, placed with precision, depict flowers and water lilies and play with the reflections of the sunlight. This vast impressionist painting is often interpreted as the surface of the rolling sea in the heart of Passeig de Gràcia.

On the first floor of the Casa Batlló, a long sandstone balcony allows us to look inside the elegant mezzanine, while the other floors have balconies in the shape of masks. And at the top, a scaly ceramic skin and turret crowned by a four-armed cross remind us of the legend of Saint George. Inside the Casa Batlló, you can visit the mezzanine, see the ceramic skylight, the double attic space with its sequence of catenary arches, and the rooftop with its colourful mosaiced chimneys. An explosion of creative freedom where Gaudí spared no effort in creating a functional and modern house.

The Casa Batlló's innovative immersive galleries take you on a completely different journey through Gaudí's mind. New technological installations and smart devices will help you rediscover this great UNESCO World Heritage Site.
