The Civico Gabinetto dei Disegni of the Sforza Castle is a resource dedicated to scientific research. The Institute is tasked with the conservation of the works that have been entrusted to it, making them available to scholars and researchers so that they may increase and divulge knowledge about them. Specialized training and an awareness of the fragility and the value of the works are imperative if they are to be consulted respecting all necessary precautions.
