Moulin de la Naze

Moulin de la Naze is a historic water mill in Valmondois, a small town in the Val-d'Oise department, set in the Oise valley right next to Auvers-sur-Oise. Today the building operates as a milling museum (Maison de la Meunerie), run jointly by the municipality and the Vexin français regional nature park.

What is this place and where does its name come from?

The mill was powered by the Sausseron, a small river running through Valmondois. In the early 20th century, the Sausseron drove as many as seven paddle wheels scattered across the village — two of them belonged to what is now Moulin de la Naze, which was formerly known as moulin Burgaud. The mill has a double wheel, a design that provided more driving power than single-wheel mills of the same size.

How old is the mill?

The oldest section of the building dates back to the 17th century. The rest was added mainly during the 18th and 19th centuries, while the wheel itself — a restored Poncelet wheel — is a 20th-century addition. The property once belonged to the estate of the Princes of Conti, a family closely tied to the region's history.

Does the mill have a literary connection?

Local tradition links Moulin de la Naze to the fabulist Jean de La Fontaine. He was a guest of the Prince of Conti, and according to the story it was during these visits that the mill inspired him to write the fable "The Miller, His Son, and the Donkey" (Le Meunier, son fils et l'âne). The claim is hard to verify definitively, but it remains a well-known part of the site's local lore and a fixture of guided visits.

What can visitors see inside?

The ground floor houses the restored Poncelet wheel along with a model illustrating how grain becomes flour through the hydraulic power generated by the mill — a hands-on lesson in water-milling that works well for children too. Upstairs, three exhibition rooms and a screening room host a rotating cultural programme: four exhibitions a year, covering contemporary artists, regional creators, or themes related to nature conservation, which fits naturally with the mill's location inside the Vexin français park.

When can you visit?

The museum is open on Saturdays from 2pm to 6pm and on Sundays from 10am to 12pm and 2pm to 6pm. Visits outside these hours can be arranged by booking in advance through the Valmondois town hall. As with many small municipal museums, it's worth planning ahead if your trip falls outside the regular weekend slots.

Who is this attraction for?

Moulin de la Naze appeals to visitors interested in the history of technology, industrial heritage, and the local culture of the Oise valley. Because it sits so close to Auvers-sur-Oise, forever associated with Vincent van Gogh, the mill is often included in day trips that combine several regional attractions — pairing the impressionist painting heritage with the story of traditional water-powered craftsmanship.

Frequently asked questions

Is Moulin de la Naze still an active mill? No, it now functions as a museum. The Poncelet wheel was restored for educational purposes rather than for producing flour for sale.

How old is the mill? The oldest part dates from the 17th century, though most of the current structure took shape during the 18th and 19th centuries.

Is it true that the mill inspired La Fontaine's fable? That's the local tradition — the poet was a guest of the Prince of Conti, who owned the estate the mill belonged to. The connection is passed down as part of the site's story, though it remains anecdotal.

Can the mill be visited every day? No — regular opening hours are Saturday afternoons and Sundays. On other days, a visit requires advance booking through the Valmondois town hall.
