Moulin de Trouguer

Moulin de Trouguer is a restored pair of windmills in Cléden-Cap-Sizun, a small commune at the far western tip of Finistère in Brittany. The mills stand just before the protected area of Pointe du Van, next to a Gallo-Roman archaeological site also named Trouguer, and they are one of the few places in the region where a working grain windmill can still be seen turning.

Where exactly is Moulin de Trouguer?

The site sits within the commune of Cléden-Cap-Sizun (postcode 29770), on the Cap Sizun peninsula, only a few kilometres from the famous Pointe du Raz. The setting is an open, windswept coastal landscape — exactly the conditions early millers were looking for. The location lies at roughly 48.058°N, 4.703°W.

What is the history behind the tower mill?

The granite tower mill was built in 1830. It was the last survivor of around fifteen windmills that once operated across the commune as far back as the 16th century, some of which doubled as visual landmarks for ships navigating the notoriously dangerous Raz de Sein passage. A violent storm tore off the top of the structure in 1945, and by 1952 the last tenant miller, Jean-Dominique Carval, had abandoned the mill entirely. After decades of neglect, the building was restored, and it has been back in working order since August 2007.

What about the second mill, Kantolor?

A second windmill stands on the same plot: a post mill (moulin-pivot), known locally as Kantolor. Unlike the tower mill, its whole body pivots on a central post so the sails can be turned to face the wind. The original post mill had vanished sometime in the 1950s or 1960s; the structure visitors see today is an identical reconstruction, brought back into operation in June 2010. Both mills are run by the local association Cap sur les Moulins, which manages day-to-day operations and visitor access.

What can visitors actually do on site?

Trouguer is set up as a hands-on heritage site rather than a static monument. Visitors can help hoist and rig the sails so they "dance" in the wind, watch the internal gearing and grinding mechanism at work, and take part in genuine flour-milling on traditional millstones. The experience is designed to be both educational and playful, aimed at visitors of all ages, with staff on hand to let children try parts of the process themselves.

When is the best time to visit?

The mills are open to visitors seasonally, from April to September; outside this window guided visits are not available. Because the site sits directly on the exposed, windy tip of Cap Sizun, it is worth bringing a windproof layer even in summer — the near-constant wind is precisely why the mills were built here in the first place.

Frequently asked questions

What's the difference between the two mills at Trouguer? The 1830 tower mill is a fixed granite structure, while Kantolor is a post mill whose entire body rotates on a post to catch the wind. The tower mill has been running since its 2007 restoration; Kantolor is a 2010 reconstruction of a mill that had disappeared decades earlier.

Do the mills still grind real flour? Yes. During the open season (April to September) staff demonstrate milling on traditional millstones, producing actual flour.

Why were so many windmills built in this area? Cap Sizun is one of the windiest stretches of the Breton coast, and the commune once counted around fifteen windmills in the 16th century, several of which also served as landmarks for sailors passing the Raz de Sein.

Who manages the Trouguer mills today? The association Cap sur les Moulins operates the site and welcomes visitors during the open season.
