The Teatro San Moisè was an opera house in Venice, active from 1640 to 1818. It was in a prominent location near the Palazzo Giustinian and the church of San Moisè at the entrance to the Grand Canal. Built by the San Bernaba branch of the Giustinian family, the first production in 1640 was of Claudio Monteverdi's (now lost) opera L'Arianna. It then passed into the hands of the Zane family and was used by the Ferrari company. The librettist Giovanni Faustini was one of the theatre's first impresarios. From the outset it was one of the smaller theatres of Venice, but also one of the most influential.
