Milan's Museum Science and Technology Leonardo da Vinci ('Museo Nazionale Scienza e Tecnologia Leonardo da Vinci') is housed in a 16th-century monastery, and features a collection of more than 16,000 items - including models based on da Vinci's engineering sketches. It's a fascinating place to delve into the mind of whiz-genius overachiever da Vinci, and learn about cutting-edge tech.
