Palau Güell displays 150 windows by Antoni Gaudí and reveals his use of light until October

Under the title Gaudí: Ventanas al Futuro, the exhibition takes over the attic of the palace and, for the first time, examines the structural and creative role of openings in his architecture. The project brings together experts and students from Tokyo and Barcelona, in collaboration with the Japanese firm YKK AP.

The exhibition allows visitors to understand how Gaudí turned windows into key features. In the building itself, constructed between 1886 and 1890, nearly 80 openings stand out along the façade. The show includes models of works such as Casa Batlló, La Pedrera and Casa Vicens, as well as videos, reproductions, and an interactive wall.

Among the most striking pieces are stained glass inspired by the Sagrada Família and the Catedral de Mallorca, alongside original elements like handles and grilles. Curator Ayano Kikuchi brings together years of research on how Gaudí combined technique, aesthetics, and comfort in every detail.

Beyond the visual, the exhibition presents a key idea: for Gaudí, windows were not just openings, but tools to connect inside and outside, regulate temperature, and make use of natural light. An approach that today is also seen as ahead of its time in terms of sustainability.

Palau Güell, one of the most representative works of modernisme, thus reinforces its role as an active cultural space in the centre of Barcelona. The exhibition turns an ordinary visit into a different experience: looking up and understanding how a seemingly simple detail can completely change the way we inhabit the city.
