Entrance to Casa Batlló on Passeig de Gràcia

Entrance to Casa Batlló, the house that Gaudí renovated on Passeig de Gràcia, and which has become the most photographed building in the city. From the street, the mosaic of the facade and the wrought iron of the balconies catch the eye, which resemble masks hanging. Inside, the pattern continues: there isn't a single straight line, and the rooms are linked to each other as if the house had grown rather than being built. You explore the rooms with their curved shapes, the wooden doors with intricate details, and the details that Gaudí designed one by one. A note about the reservation: this ticket is non-refundable.
