Moulin de Crémeur

Moulin de Crémeur is a stone windmill standing north of Guérande, along the road to La Roche-Bernard in the Loire-Atlantique department of Brittany. Locals also know it as the Moulin du Diable — the Devil's Mill — a nickname that hints at the legend behind it.

What kind of building is this, and why visit it?

The mill is a classic example of a Breton "petit pied" windmill: a low, compact stone tower with sails reinforced by crossbars (ailes à barreaux). This design was once common across the whole Guérande peninsula, where steady Atlantic winds turned the millstones that ground grain for surrounding farms for centuries. Despite its modest size, the stonework is well-fitted and solidly built, a sign of skilled construction. The mill has been listed as a French historical monument since 7 January 1901, confirming its standing as a piece of local heritage.

What is the history behind the mill?

Its roots go back to the late 15th century. At the time, the Crémeur seigneury belonged to Tristan de Carné (1476–1536), who was appointed captain of Guérande in 1513 by Duchess Anne of Brittany. The mill kept turning until the end of the 19th century, grinding grain for nearby villages — one of many windmills, alongside others in La Turballe, Le Croisic and Batz-sur-Mer, that once powered daily life across the peninsula.

Why is it called the Devil's Mill?

According to local legend, a miller named Yves Kerbic wanted to build his own mill but was too poor to afford one. The Devil appeared and offered a deal: he would build the mill in a single night if Kerbic handed over his soul in return. Kerbic agreed. The Devil worked through the night at supernatural speed, stone by stone — but when the church bells rang the morning angelus, one stone was still missing. Thinking fast, the miller placed a small statue of the Virgin Mary in the empty niche and made the sign of the cross. Defeated by the holy sign, the Devil fled, leaving the mill forever missing that one stone yet fully able to work. The tale is still told across the peninsula today and is one reason the mill became a favourite subject for postcards and one of the area's most recognisable landmarks.

Can you go inside the mill today?

No — the building is in poor condition and is not open to visitors. The interior remains inaccessible, and its windows were altered at some point without much regard for the original design. That said, the surrounding grounds let you walk right up to the tower and its sails for a close look and photos, making it one of the most photographed spots near Guérande.

How do you get there, and what else is nearby?

The mill sits on the road between Guérande and La Roche-Bernard, making it an easy stop when exploring the walled medieval town of Guérande and the nearby salt marshes (marais salants). Nearby, other windmills in La Turballe, Le Croisic and Batz-sur-Mer make it possible to piece together a small windmill trail across the Guérande peninsula's distinctive landscape.
