Finding and Uncovering Hidden and Secret Canals, Bologna
Finding and uncovering the hidden secret canals in Bologna was an adventure. You actually bump into people doing the same exact thing as you are; it’s quite funny actually.
Bologna has 37.29 miles or (60 km) of mostly covered over canals. As early as the twelfth century the city provided itself with a hydraulic system consisting of locks, canals and underground pipes that distributed the water which was used mainly as an energy source for trades.
In the 1930s the navigable canals were covered.
There are a few hidden canals that can still be scen in a certain area of the city. There is even what they call a “Secret Window”.
