Recinte Forum

The Forum Building in Barcelona is an architectural landmark designed by the Swiss architects Jacques Herzog and Pierre de Meuron. The triangular structure, 25 meters tall, stands at the intersection of Diagonal Avenue, Rambla de Prim, and Ronda Litoral. Originally conceived as a symbol of the Universal Forum of Cultures in 2004, the building was politically controversial because of its cost and the defects that surfaced during construction. Since 2011, it has housed Barcelona's Museum of Natural Sciences, previously known as the Museu Blau. Inside, you can explore a large exhibition hall of nearly 5,000 square meters as well as an auditorium with 3,200 seats, both used for cultural and scientific events.
