The history of Milan and the development of the most important cities for trade and industry has been possible thanks to the birth of the system canals Navigli. The network of waterways that run through Milan, allowed the river transport between the Ticino, the Adda and the Po flowing into the Adriatic Sea.
On the banks of canals lived workers and artisans. Even today, the ancient workshops and historians washrooms, covered with wooden roofs, remind us of a Milan disappearance.
