|The Navigli area in Milan is very central and frequented by locals who cross the bridges on their way to work, as well as by tourists who come to see this historical place. Along the canal are small shops, cafes and artist studios. The combination of street, pedestrian walks, water and the different kind of visitors made it an ideal location for playing on public objects.
The Naviglio Grande was the first artificial canal in Europe and the most important of the Milan “navigli”. [Wikipedia]
Since the 13th century the canal had been a main way for transporting goods between the Lago Maggiore area, Switzerland and Milan. It was in use until the 1960ies, and since then has only been used for irrigation in agriculture.
