ABSTRACT
Since the middle ages, local communities which were able to channel water, organized water powered manufactories and mills, creating over time what were actual “pre-industrial districts”, indivisibly bound to the network of channels that drove the vertical or horizontal blades of the millwheel. Canals, watercourses and waterfalls were as much as factor of production as the land and iron, coal and silver mines, and with time, communities learned to exploit water power with increasing efficiency. Water is by its very nature highly dynamic, and as a consequence, since ancient times, human activity has been directed at taking advantage of it power. The Tuscan case studies in point—Calci (Pisa), Rio dell’Elba (Livorno) and Colle di Val d’Elsa (Siena)—still legible on the land, even if confusedly, vouch for the value of the work culture and that of the land and environment, which belong by right to the resident community.
