Moulin de Rimaison

Moulin de Rimaison is a historic water mill on the Blavet river, in Pluméliau-Bieuzy, in the Morbihan department of Brittany. It stands in the hamlet of Rimaison, right next to lock no. 6 on the canalized stretch of the river, and ranks among the best-preserved mills in the Blavet valley.

What is the history behind the mill?

The mill was built in 1556 on the orders of Michel de Rimaison, lord of the nearby château, to grind grain into flour. During the French Revolution it was seized as national property, and in 1799 it was sold to the Poullic family, who took over its operation. When the Blavet was canalized in the 19th century, a dam was built in 1862 specifically to preserve enough water flow for the mill to keep running despite the changes to the riverbed. In the second half of the 19th century, a separate house was built just north of the mill to serve as the miller's residence. The mill kept working for centuries and only stopped operating in the 1960s.

What does the building look like, and what makes it distinctive?

The mill is built of dressed stone, combining slate and granite. It has a ground floor topped by a habitable attic fitted with a fireplace. The layout is functionally split in two: the eastern part of the building housed the milling machinery, while the western part served as living quarters. The most striking feature is the carved decoration on the gable of the western façade. On the southern side, a relief depicts Hercules holding his club; on the northern side, a mermaid. Two lions are also set into the gable, bearing the coat of arms of the Rimaison family, topped by a helmet, which in turn is crowned by a half-length figure of an angel. This elaborate heraldic decoration makes the mill an unusual example of industrial architecture, one that combined a working function with the prestige ambitions of the family who commissioned it.

Why is the mill a protected historic monument?

Given its historical and architectural value, Moulin de Rimaison was listed as a monument historique by decree on 4 March 1994. The protection covers both the mill building itself and its distinctive stonework, recognized as evidence of the region's past industrial activity along the Blavet valley.

What else is there to see nearby?

The mill sits close to Rimaison Castle, whose grounds today host a golf course, and the surrounding area is now part of the Blavet valley's tourist trails. A walking route, the "Circuit de Rimaison," and a cycling path along the river both pass through here, popular with visitors exploring the stretch between Pontivy and Bieuzy. Lock no. 6, next to which the mill stands, is part of the canalized Blavet's navigation system, still used today by tourist boats and canoes.
