In the 19th century Palazzo Bonacossa, a stone's throw from the Castello Sforzesco, the Museo d'Arte e Scienza offers the two Leonardo rooms and the splendid Sala degli Arazzi, equipped with all the computer systems necessary for meetings, conferences, screenings and presentations, company conventions, chamber music concerts and temporary exhibitions. The Museum houses the permanent collections of the Matthaes family: the Buddhist Art exhibition, the African Art collection and the educational section on Authenticity in Art and Antiques.
