A cluster of traditional stone flour mills along the Deva river, restored as a small ethnographic park on the edge of Arbo village. Local families used these water-powered mills to grind corn for generations, and the restoration has preserved the millstones and wooden mechanisms in working order. Demonstrations run during the main season.
The setting along the riverbank is pleasant enough to justify a short stroll even if you arrive outside demonstration hours. Arbo is best known for its lamprey fishing, and the mill park fits naturally into a half-day visit to the area.
