The auditorium consists of three concert halls with 2,700, 1,200, and 700 seats, an open-air arena, a museum for musical instruments, a library, restaurants, offices, and service facilities. Renzo Piano designed the modern architecture by combining it with typical Roman building materials such as travertine, terracotta tiles, and curved lead roofing. It is located in the Parioli district on Via Flaminia.
