Milan, the "moral capital" of the Kingdom, displayed a collection of 387 items, consisting mainly of printed works (editions of texts by Cavalieri, Salvatico, Castiglione, Boscovich, etc.). A small section devoted to Alessandro Volta was set up thanks to the contribution of Francesco Somaini. In Florence, Milan appeared as the symbolic city of modern industrial enterprise. Its hall was occupied, in fact, by electric engines, models of locomotives, generators, transformers, etc. The City of Milan also sent an aeronautical collection donated by Achille Bertarelli. The members of the Milanese committee included, among others, Carlo Calzecchi Onesti, Tommaso Gnoli, Emilio Bianchi, Ruggero Bertola and Giovanni Galbiati.
