Leonardiana is the place, unique in the world, where the visitor can admire all the large and heterogeneous work of one of the greatest geniuses of humanity. The Museum offers an unprecedented itinerary through the life and work of Leonardo who stayed in Vigevano as superintendent of the waters on behalf of Ludovico il Moro, but also as a member of the court of Ludovico and Beatrice who always appreciated his exquisite artistic skills, the worldly attitude and the scientific and mathematical genius. The Museum exhibits all the work that Loenardo was able to conceive and create in the course of his life: the drawings, now preserved in dozens of museums and libraries around the world, the notebooks that accompanied his days, full of his thoughts and brilliant intuitions, the codes that after his death were assembled by his friends and heirs and which today are kept in the largest libraries and institutions in the world. The exhibition itinerary is completed by the "impossible art gallery", in which all 26 paintings recognized to his hand are exhibited, reproduced in full scale with special high-resolution techniques, which allow the visitor to immerse himself in the totality of the work, a unique experience that will allow a close and in-depth analysis of his artistic language.
