This huge neoclassical palazzo was originally built in 1882 as an exhibition center; it has since served as headquarters of the Italian Communist Party, a mess hall for Allied servicemen, a polling station and even a public loo. Nowadays it's a splendid cultural hub, with cathedral-scale exhibition spaces hosting blockbuster art exhibitions. There's a large art bookshop, a study hall, a cinema, a cafe with a small courtyard and a swish, glass-roofed restaurant.
Occasional concerts, performances and film screenings are also held here.
