They say there’s a big difference between cities that have or don’t have a river running through them . They say water takes away negative energy, and waters being trapped underneath (like in Bologna and Milan, for instance) would be better off if out in the sun. This is Bisenzio, the river of Prato. It is now such a beautiful place for strolls or just sitting and watch the flow. Old people smile at the thought of its transformation: they say it used to change color every day because of materials being colored, when economy was allright and factories worked at full capacity.
