Parque da Natureza do Río Barosa, Natural park and waterfall system in Barro, Spain.
The Parque da Natureza do Río Barosa is a nature park in Galicia with a waterfall and 17 traditional water mills spread along the Agra River. The mills sit close together and once formed a working system where water flowed from one to the next downhill.
The water mills were built starting in the Middle Ages and adapted over centuries to serve local needs. Most were abandoned in the 20th century when modern machinery replaced traditional grain processing.
The mills show how communities in Galicia used water power for centuries to grind grain and process food. Visitors can still see today how closely this work was tied to the rhythm of nature and the seasons.
The park has marked walking trails that are easy to follow, and picnic tables along with natural pools are scattered throughout. A restaurant near the main waterfall serves local dishes and provides a good place to rest during your visit.
The mills are connected to each other and functioned as a network where excess water from upper mills automatically flowed to lower ones. This made the system particularly efficient and shows engineering skill that is rarely seen today.
