Casa Batlló is one of the most representative works of Catalan modernism and one of the most admired buildings in Barcelona. Located on Passeig de Gràcia, this creation by Antoni Gaudí stands out for its undulating and colorful façade, inspired by natural forms. Initially built in 1877 by Emilio Sala Cortés, it was renovated by Gaudí between 1904 and 1906 for Josep Batlló, who granted the architect full creative freedom allowing him to transform the building into a unique piece within the urban landscape of Barcelona.
This architectural jewel not only attracts attention due to its formal uniqueness, but also its constant reinvention. Now, it is a benchmark in the intersection between art, heritage and technology thanks to the mapping shows. These project moving images on its façade allowing the building to be rediscovered from a contemporary perspective, establishing a dialogue between Gaudí’s legacy and current artistic trends.
Casa Batlló in the 21st century
Gaudí’s legacy has been kept alive thanks to the reinterpretation of his work. Casa Batlló has historically been a symbol of modernism, but in recent years it has adopted new artistic languages to maintain a connection with the public. Mapping is a key tool in this transformation, incorporating elements of light, movement and interactivity, giving the building a new expressive dimension.
This technology amplifies the narrative and allows us to explain the history of the building from different perspectives. In addition to highlighting heritage, these projections promote a dialogue between tradition and innovation, offering an immersive experience that brings Gaudí’s architecture closer to new generations.
Digital art takes Passeig de Gràcia
Every year, Casa Batlló becomes a canvas on which international artists project their vision through mapping shows. The building becomes a fusion of architecture, digital art and technology, creating unique experiences that transform the perception of its façade.
Since 2023, mapping creators have attracted thousands of viewers with their innovative ideas. The first edition in 2023 saw Refik Anadol presenting Living Architecture, a mapping that used real-time climate data to generate dynamic visual patterns that reflected the changing nature of the city. In 2024, Sofía Crespo explored biodiversity through artificial intelligence with Structures of Being, a work that projected forms inspired by natural organisms.
In 2025, Quayola introduced Arborescent, a proposal transforming the façade into a digital plant landscape, creating an illusion of growth and movement that merged art and nature. The show, which was held in February, brought together more than 110,000 spectators in Passeig de Gràcia. His visual creation, simulated the growth of trees and plants that highlighted the dialogue between heritage and innovation, offering a new way of experiencing architecture.
A new immersive visit
The modernist house not only bets on high tech displays on its façade. It has revolutionized the visits to the building through a truly unique immersive experience. Using technologies such as augmented reality, artificial intelligence and volumetric projection your five senses are immersed in the universe of Gaudí through. This new tour includes 2,000 m2 of completely new spaces, stories in 15 languages and a soundtrack performed by members of the Berlin Philharmonic.
Among the most outstanding is the Gaudí Dome, a room with more than 1,000 screens that recreates the childhood and the sources of inspiration of the architect through natural images and sounds. In addition, the Gaudí Cube, by Refik Anadol, offers visitors the chance to symbolically enter Gaudí’s mind thanks to a six-sided LED cube that projects images generated with artificial intelligence based on Gaudí’s original work.
A bridge between generations
Casa Batlló has become a model of how heritage can be transformed without losing its essence. Mapping, augmented reality and immersive spaces have allowed modernism to be reinterpreted, making it more accessible and attractive for new generations. This has been recognized by international awards such as the Remarkable Venue Award 2021, which distinguished it as the best monument in the world above icons such as the Tower of London and the Duomo of Milan.
In addition, the space has demonstrated its commitment to inclusion and accessibility by incorporating neurodivergent people into its visitor service team in collaboration with Specialisterne. This initiative reinforces the vocation of Casa Batlló to be an open and dynamic space, capable of communicating its historical value through innovative experiences.
