A Rationalist-style building put up between 1930 and 1934 to a design by the municipal engineer Luigi Onorati — the same man who designed the seafront. Opened on 1 September 1934, it is blue, as its name says (azzurra). In the boom years it hosted shows by the most fashionable performers; after its 1996 restoration it returned to being a cultural centre, with photography and contemporary-art exhibitions. It's one of the town's symbols.
