Leonarda Da Vinci is an exhibit which presents over 30 models of mechanical, bulding, flying and war machines, exactly reproduced from Leonardo da Vinci' codices (Atlantico, Madrid, Trivulziano, etc.). The machines have been made in wood, metal and fabric, on scale or life-size by clever and qualified florentine artisans under expert engineers supervision. What more attracts the pubblic is the interactive characteristics of the machines, which means the visitors can touch and handle the models seeing them working. Over 30 explanations (one each model), 10 illustrative panels, the copies of the codices (free to be used) keep sharp the scientific and cultural level of the exhibit.
