Popular tradition has it that the name Cadenazzo derives from the chains used to link the boats that travelled down the Ticino to Lake Maggiore. At the time the river did not have artificial banks and the surrounding land had not been reclaimed, so it’s bed was much wider than today.
Until a few years ago, children often challenged one another by racing their paper boats down rivers to see which was the fastest. Who can still remember how to make a paper boat today? Follow the instructions shown in the figure to make your own.
