Moulin Bonnet

Moulin Bonnet is a historic windmill standing on the slope of the Montagnette massif, right above the village of Boulbon in the Bouches-du-Rhône department of Provence. Its stone tower and wooden sails are visible from a distance, making it a recognisable landmark among the surrounding olive groves and vineyards.

Where exactly is Moulin Bonnet, and why there?

The mill stands on the western slope of the Montagnette, overlooking the village and plain of Boulbon below. This position was no accident: that side of the massif is well exposed to the mistral, the strong, steady wind blowing down from the north that powered Provençal grain mills for centuries. Sitting there let Moulin Bonnet run efficiently in a landscape where water-powered mills had no real chance.

How old is the windmill?

The construction date usually given is 1776, though restoration work uncovered an earlier date, 1748, carved into one of the millstones. The discrepancy suggests the mechanism may have started life elsewhere or that the mill was rebuilt more than once during the 18th century — either way, Moulin Bonnet dates back to the period when windmills were central to the local grain economy.

What happened during the restoration?

The mill underwent a full restoration in 2003. The tower, which had lost both its roof and its sails over time, had them rebuilt, and the entire milling mechanism was reconstructed by carpenters specialising in traditional millwork who came from the upper Var. Once the work was finished, Moulin Bonnet became the first windmill in the Bouches-du-Rhône department to be brought back into working order — not just preserved as a static monument, but returned to actual operation.

Does the mill still work?

Yes. The sails of Moulin Bonnet are set turning on days when the mistral blows, which are close to the conditions the mill originally relied on. That makes a visit here a rare chance to see a genuine milling mechanism in something like its natural working state, rather than a mothballed exhibit.

When can you visit Moulin Bonnet?

The windmill opens to visitors on the second and fourth Saturday of the month, from 2 pm to 5 pm, outside the summer period. Tours are led by volunteer millers who maintain the mill and keep it running — they explain both the mechanics of the mill and the history of the site to visitors.

What else is worth seeing nearby?

Boulbon is a small village at the foot of the Montagnette, surrounded by classic Provençal scenery: olive groves, vineyards, and dry, stony hillsides. Thanks to its elevated position on the slope, Moulin Bonnet also serves as a natural viewpoint over the village and the plain below, making it a good short walk on its own or a stop along a longer hike through the Montagnette.
