In 1878 Baron Raimondo Franchetti (1829–1905), who had married Sarah Luisa de Rothschild (1834–1924), daughter of Anselm Salomon Rothschild of the Vienna Rothschilds, bought the palazzo and commissioned further works by architect Camillo Boito, who constructed the grand staircase. In September 1922 it was sold to the Istituto Federale di Credito per il Risorgimento delle Venezie by Franchetti's widow.
