The Museum on the first floor of Palazzo Morando Attendolo Bolognini is divided into two distinct routes: the Art Gallery, set up in the rooms facing the internal courtyard, and the noble apartments overlooking Via Sant'Andrea.
The Art Gallery preserves an important iconographic collection that illustrates the transformations of the urban fabric and the main manifestations of public and private life in the city of Milan between the 17th and the beginning of the 20th century.
Coming from Luigi Beretta's collection, acquired by the Municipality in 1934, these works found their first home in Palazzo Sormani under the name of the Museum of Milan.
After the Second World War the Museum was moved to the rooms of Palazzo Morando Attendolo Bolognini, bequeathed to the municipality by Countess Lydia Caprara di Montalba together with the furnishings, works of art and decorative art objects contained therein. Next to the art gallery there is a series of rooms in which it is possible to admire the taste for furnishings between the eighteenth and nineteenth centuries.
