Big Staircase leading to the Upper Floor or the Iron Staircase

The southwest staircase with wrought iron balustrades, link the south end of the porch to the various areas of the main floor. The frescoed walls, distributed in different levels, exhibit a rich collection of aristocratic coat of arms and constitute an interesting example of Lombard heraldry, affirming the importance achieved by many noble families who were in touch with the Cesano way of life. Far from interpreting them as sterile decorative elements or unnecessary ostentation of power, family crests help in understanding society as it was in the 16th-17th centuries and its different forms of government. In particular, they confirm the position of great fame and wealth attained by the owners of the building, as a result of the shrewd policy of marriage alliances and the agreements that governed political and economic friendships.
