This 2026 one of the most iconic buildings in the center of Madrid celebrates its centenary. It is the headquarters of the Círculo de Bellas Artes (CBA), a private, non-profit cultural institution that claims to be a "reference of freedom and independence" in the capital of the State. In recent years, it has focused on "opening up to citizens" with initiatives such as the climate shelter —they have set up a green and free space that last summer was used by 60,000 people to protect themselves from the heat; the Festival of Ideas, which brings philosophy to the streets, or the City and Science Biennial, organized in collaboration with the Barcelona City Council.
