Ca' Giustinian is the result of the union of two different buildings: Giustinian (1474) and Badoer-Tiepolo. During the 16th century, they were combined in one, thanks to the internal adjustment of masonries and attics. The famous leader Giovanni dalle Bande Nere stayed there, when he was working for the Serenissima Republic.In 1750 it passed from the Giustinian family to the Morosinis. In 1817 it was acquired by Arnold Marseille, who turned it into a HOTEL de l’Europe”, that hosted among its guests: Giuseppe Verdi, who used to occupy a room with a private drawning room and a piano, where his operas Ernani (1843) and Rigoletto (1851) were partly written.Acquired in the 30’s of the 20th century by the City of Venice, whose plan was to settle its casino there, the palace underwent several major changes, as the addition of the Sala delle Colonne, realised on the first floor, facing San Moisè Church. Right after the war, it became the headquarters of the Biennale as well as of the municipal tourism offices.In the 50’-70’s the Sala delle Colonne was intended as an open space for conferences, concerts, cultural and political events, on an almost daily basis. The last floor hosted the city’s cinema club until the end of the 70’s.
