L’Auditori is the heart of music in Barcelona, thanks to its four concert halls and a programme of more than 450 concerts per year. It is the home of the Barcelona Symphony and Catalonia National Orchestra, which, under the direction of Kazushi Ono, presents great symphonic repertoires with internationally renowned soloists and conductors. L’Auditori also has a very significant programme of early music, as well as a prestigious programme of chamber music. The Museum of Music and Catalunya College of Music also form a part of this grand musical centre, which is unique in its notable musical quality and excellent acoustics. L’Auditori also include an extensive social programme with an educational service aimed at audiences of all types, helping to make culture accessible to all under the leadership of the Apropa Cultura programme.
L’Auditori is a modern building with premises covering 42,000 square metres. Designed by the architect Rafael Moneo, it was officially opened on 22 March 1999. 
It is situated at the heart of the new area of urban development in Plaça de les Glòries and the innovation district 22@. It is very closed to Torre Agbar (Jean Nouvel), the Teatre Nacional, the Disseny Hub Barcelona and the Sagrada Família. L’Auditori is thus a focal point for the dissemination of music in Barcelona and education and research in this field.
Since December 2007, l’Auditori has been part of the European Concert Hall Organization (ECHO), the most prestigious association of auditoriums in Europe, and was the first concert hall in Spain to become a member.
