"Re-learn" and "Re-value" are the keywords at the base of the sustainable exploitation strategy of cultural heritage, little known but highly cultural and environmental valid, belonging to Southern Italy, already colony of Magna Graecia. The main goals are to "spread" the knowledge of the territory, "enhance" the sense of belonging to a new physical and cultural reality, "develop" the perception of a new metropolitan reality and "promote" the enjoyment of the environment, aiming at a careful and conscious cultural tourism. Within the tourism network, our idea tends to include particularly significant and representative sites of Campania's history and culture, little known ones such as Campi Flegrei, Sorrento and Amalfi Coasts, Liternum, Nola, Cimitile, Amalfi, Agerola, Gragnano, etc. The present case study concerns, in particular, the Valle dei Mulini ("Mills valley") in Gragnano, which is an example of proto-industrial archaeology dating back to the twelfth century as well as an old dirt road connecting with Amalfi republic. This site is featured by canals carved into the rocks, which lead water directly to the mills towers, capable of converting the pressure of the hydraulic machine movement into useful energy. More in detail, the sustainable aspect of this project foresees the production of electricity by exploiting the mechanism of the falling water in water towers, giving rise to the grindstone rotational motion which is turned into electrical energy. The water flow passes from one tower to another one, placed at a lower altitude, and then moves on to the next one. Therefore this strategy would enhance the whole eco-system, by means of site remediation and artifacts restoration, in order to place this resort in the tourism / hospitality circuit and trigger a sustainable process aimed at its future safeguarding.
