The palace was built from 1557 to 1563 for Tommaso Marino.C. Casati, Nuove notizie intorno a Tomaso De Marini, "ASL" 1886, pp. 584–640T. Sandonnini, Tommaso Marino mercante genovese, "ASL" 1883, pp. 54–84 It was designed by architect Galeazzo Alessi from Perugia. Its main facade originally faced Piazza San Fedele, as Piazza della Scala at the time was a warren of medieval houses.C. Baroni, Documenti per la storia dell'Architettura a Milano nel Rinascimento e nel Barocco, vol. II, Accademia dei Lincei, Rome 1968, pp. 398–424 The construction was occasionally slowed down by the opposition of the population, that had a very conservative attitude towards the architecture of the centre of Milan.G. Marangoni, La casa del Comune di Milano: Palazzo Marino, in "La cultura moderna", September 1925
