The Academy of Fine Arts ( Accademia di Belle Arti) and the Gallerie dell'Accademia occupy the former church and convent of Santa Maria della Carità, which retains a Gothic doorway surrounded by relief sculpture, dating from 1377, and the Scuola della Carità founded in 1260, the existing Baroque facade being by Giorgio Massari. The former church was rebuilt by Bartolomeo Bon the Elder in the mid fifteenth century, while the inner courtyard of the existing complex is attributed to Palladio. It contains the largest and most important collection of Venetian art in existance. This includes works by, amongst others, Titian, Tintoretto, Veronese, Giovanni Bellini and Gentile Bellini, Carpaccio, Cima, Piero della Francesca, Giorgione, and Canaletto. The basis of the collection is that of the Academy, founded by Giovanni Battista Piazzetta in 1750. The collection was moved to its current premises by Napoleon in 1807 and considerably augmented by works taken from religious institutions and churches which had been suppressed. Ruskin 's visits to the Accademia included those made on his Venetian visits of 1841, 1845, 1846, 1869, 1872 and 1876-77. He studied there the works of Gentile Bellini, Giovanni Bellini, Carpaccio, Tintoretto and Titian. He wrote The Guide to the Principal Pictures in the Academy... at Venice in 1877 ( Works, 24.139-90).
