There are almost 20 water mills in a good conservation state in the region, including hydraulic structures, which have been documented by photos and schedules. Some fulling mills were converted into grinding mills during the 19th century, probably for economic advantages (Grano, 2020). Only a few grinding mills with horizontal axis were found.
