We were fortunate to discover A museum devoted entirely to the inventions of Leonardo DaVinci. It was only a 5 minute walk from our apartment. The brilliance of this genius was clearly on display in the countless models throughout the museum ( such as the mobile multi-canon device shown in the first picture. This was to be mounted on a ship and all of the canons had to be fired at once to keep the ship stable. It was reportedly the precursor to modern day tanks). Many of the exhibits were hands-on allowing the visitor to fully appreciate the inventions. Included in the tour was a 100 minute History Channel video depicting DaVinci's life and works. We thoroughly enjoyed spending the day there.
