The Museumís collection of historic Leonardesque models was created to celebrate the fifth centennial of Leonardoís birth. A group of experts was nominated to study Leonardo da Vinciís manuscripts in order to create the models which were displayed for the first time in 1953. In Leonardoís drawings there are not only projects of machines to be built but also observations of existing works, suggestions for improvement or studies on nature. The models on display are the fruit of a reinterpretation which has translated and completed his drawings. The historic layout of the Leonardo Gallery, where the exhibition of the models is enriched with a series of drawings from his numerous fields of interest, is completed with an exhibition that examines more closely his Milanese years.
