Unlike the rest of the Cycladic islands, Andros offers abundant fresh water, so it was inevitable for the locals to use the power of water.

A large network of watermills was developed as the use of water as a driving force, comparing to wind, offers the advantage of stability and control operating regardless of weather conditions.

More than 40 watermills, excellent samples of pre-industrial technology, survive in Korthi region. Most of them are in the Dipotamata Gorge, but there are also in Aidonia, Vouni, Piso Meria, Episkopeio and Rogo settlements.
