Palazzo Dolfin Manin is a palace in the sestiere of San Marco on the Canal Grande of Venice, northern Italy. It is located near the Palazzo Bembo, not far from the Rialto Bridge. The palace was built by the noble Dolfin family starting from 1536, in order to renovate their previous residence, formed by two separate medieval edifices. The construction cost some 30,000 ducats, and was designed by Jacopo Sansovino. A renovation program was carried on under the last Venetian doge, Ludovico Manin, who commissioned the works to Giannantonio Selva. Ludovico Manin spent here in segregation his last years, after signing the Treaty of Campoformio which ended the Republic of Venice.
