Designed by starchitect Renzo Piano and inaugurated in 2002, Rome's flagship cultural center is an audacious work of architecture consisting of three silver pod-like concert halls set around a 3000-seat amphitheater. There's a pleasant cafe in the central square and the grounds include a children's park. There's also a good book and music store.
Excavations during its construction revealed remains of an ancient Roman villa, some of which are now on show in a small museum.
English-language architectural tours of the complex (adult/reduced €9/5) are conducted on Saturdays (12.30pm) and Sundays (12.45pm). Call ahead to check availability.
