The “Gottffied Matthaes” Museum of Art and Science is located inside Palazzo Bonacossa in Milan. Inside the museum there is a very varied art collection: Greek - Roman and Etruscan, African and Buddhist. The Matthaes family's collecting has led the museum to have a large collection. Another theme that was developed by Gottfried Matthaes is the False Art. In fact, in the 90s he founded an "Educational Museum for the verification of the forgery in the antiquarian". Today there is a real scientific laboratory "Authentic Art" specialized in spectroscopic dating. Currently the museum hosts temporary exhibitions and specific educational sections to bring all ages closer to the museum.
