The Auditorium San Fedele in Milan is one of the city's most original and refined cultural venues. Located in the historic center, just a few steps from Palazzo Marino and the Duomo, it is much more than just a concert hall. Inaugurated in the 1950s as part of the Jesuit complex, the space stands out for its sober yet avant-garde architecture and is famous not only for its shell-shaped structure, which guarantees an optimal view from every seat, but above all for its excellent acoustics. In fact, the Auditorium houses the only mobile Acusmonium in Italy: a sound projection system consisting of dozens of speakers of different sizes and timbres. The aim was to create a ‘sound control room’ in the space, allowing the listener to be literally immersed in the music. This technology has made it a Milanese landmark not only for classical music but also for experimental and contemporary electronic music, cinema, and contemporary art.
