Its seating capacity is 10,300, rising to 13,000 for concerts, which makes it the fifth-biggest indoor arena in Italy.

The venue was inaugurated with a recital by operatic tenor Luciano Pavarotti.

The venue considered a futuristic construction, known to most as "the Spaceship" (l'Astronave), or as "the Ladybug" (la Coccinella) due to its external shell shape.

The multi-purpose arena is equipped with a press stand, a room for video data, a system for satellite reception, various video stations and an internal circuit control system.

The venue also configures into a (much smaller) theater that is used each August for the world-renowned Rossini Opera Festival.
