Hydraulic power, the only reliable source of energy, intensified in the 19th century. Here you will come across the Kerrousseau mill, already in use in 1671 and built on the stream of the same name, then Frémeur mill, on the Pont-Scorff side on the Scave river. Only ruins remain, but a flour mill known as Kerruisseau exists further downstream on the departmental road.
