Moulin à eau (ancien)

Moulin à eau (ancien) in Villar-Loubière is a historic water mill sitting at roughly 1,060 metres above sea level, deep in the Valgaudemar valley in the Hautes-Alpes. It is one of the few mills of its kind in France that has been restored to working order, giving visitors a rare chance to see how mountain millers actually worked before electricity reached these valleys.

When was the mill built?

The building dates from 1838, part of the wave of rural mills constructed in the second quarter of the 19th century. For generations it belonged to the Bellon family, who ran it to serve local farms with flour and oil. In 1978 ownership passed to the Écrins National Park, which secured the building's future, and on 21 March 1983 the mill was officially listed as a historic monument.

What does the mill look like, and how did it work?

The roof was originally thatched, a common covering in this part of the Alps before slate and sheet metal took over. The structure was restored in 1979, and the municipality renewed the roof again in 2000 while keeping its traditional appearance.

Inside, the mill uses a drive system typical of Alpine water mills: a canal channels water onto three horizontal wooden-paddle wheels, each dedicated to a different task. One powered the oil press used for walnuts and hazelnuts, a second ground grain into animal feed, and a third produced flour for household use. A fourth wheel, mounted vertically and now reduced to its axle, once drove a sifter that separated flour from bran.

Is the mill still operating?

Yes. Since 2013 the mill has been fully functional again and is regularly demonstrated in action, producing flour and pressing walnut and hazelnut oil in front of visitors. That matters because the Valgaudemar valley once counted 23 mills, and this is the only one still capable of showing that traditional milling craft at work.

Who looks after the mill today?

The site is maintained by a local association, Moulin, Patrimoine et Culture en Haut Valgaudemar, founded on 12 January 1999 to study, protect and promote the technical and cultural heritage of Villar-Loubière. The mill building also houses a small museum dedicated to the history of milling in the region.

Why visit?

The Moulin à eau in Villar-Loubière offers a rare close-up look at a working water mill set within a high-mountain village inside the Écrins National Park. A visit pairs easily with the wider appeal of the Valgaudemar valley, known for its hiking trails and views of the Écrins massif, alongside a hands-on lesson in the craft that once kept mountain communities fed through the winter.
