This magnificent palace, now museum of 18th century Venice, was designed by the greatest Baroque architect of the city, Baldassare Longhena for the aristocratic Bon family, and works began in 1649. Giambattista Rezzonico, merchant and banker, bought the palace in 1751 and appointed Giorgio Massari, one of the most highly esteemed and eclectic artists of the day, to complete the works, which proceeded rapidly and in 1756 the building was finished. While the magnificent facade on the Grand Canal and the second floor followed Longhena’s original project, Massari was responsible for the audacious inventions towards the rear of the palace: the sumptuous land-entrance, the ceremonial staircase and the unusual grandiose ballroom obtained by eliminating the second floor in this portion of the building. As soon as the building was completed, the most important painters in Venice were called upon to decorate it: Giambattista Crosato, who painted the frescoes in the ballroom together with the trompe l’oeil painter Pietro Visconti; Giambattista Tiepolo, who painted two ceilings in celebration of the marriage between Ludovico Rezzonico and Faustina Savorgnan; the young Jacopo Guarana and Gaspare Diziani. The building was fully complete by 1758, when Giambattista Rezzonico’s younger brother, Carlo, Bishop of Padua, was elected Pope under the name Clement XIII
