If you want to get to know Leonardo's genius better, you cannot miss a visit to the Museo Scienza e Tecnologia Leonardo da Vinci (Leonardo da Vinci Museum of Science and Technology), located near the place where Leonardo owned some vineyards.
The museum, housed in the ancient rooms of the monastery of San Vittore, holds the largest collection in the world of machine models made from the designs of the Genius from Tuscany.
To reach the Museum from Piazza Santa Maria delle Grazie, go back in the direction of the Casa degli Ateliani museum and Leonardo's vineyard, cross Corso Magenta (paved crossing, sometimes uneven, with tram rails), take via Bernardino Zenale on the right sidewalk (at first it is only 90 cm wide and delimited by iron stakes, then after 50 meters it becomes very wide), go along it for about 200 meters and turn left in via San Vittore. The sidewalk, on the left side of the street, is quite wide.
Continue for about 150 meters and when you reach number 14 of via San Vittore, cross the road using the pedestrian crossing (crossing in uneven paving, with tram rails) and go immediately to the right on the opposite sidewalk and then turn the corner on the left and you will find yourself in the square where the museum entrance is located.
