A bit of history... The mills of the Sorgue

In the 18th century, there were 11 paper mills employing 500 people in the Vaucluse region. Four of these mills were established in Fontaine-de-Vaucluse.

The first implantation of a paper mill on the banks of the Sorgue dates back to 1522 with the Moulin du Martinet. Transformed into a silk production plant in the 16th century,  then to a  wool carpet plant in the 19th century, it regained its role as a paper manufacturing site around 1920 following its acquisition by Valdor-Prioux. It ceased all activity in 1968.

At the end of the 16th century, close to the site of the Martinet mill, the Moulin du Pont, which had two wheels, was established. Around 1653 the owners of the Martinet mill built a second mill, the Moulin du Fond.

In the 19th century, another mill was installed, the Moulin du Prés, annex of the Martinet factories.  It  was  closed in 1968. All these mills disappeared in the middle of the 20th century. A last mill on the banks of the Sorgue, the Moulin of the Fountain was established in 1862. It would have suffered the same fate if an ambitious project had not allowed his rebirth.

Vallis Clausa

In 1973, at the request of Jean Garcin, President of the General Council of Vaucluse, Marius Péraudeau, founder of the Richard de Bas paper mill and curator of the historical museum of Ambert, Auvergne, imagined and created a cultural and artisanal grouping in Fontaine-de-Vaucluse.                                                                  

Its goals were: to renovate and safeguard the last papermill on the Sorgue, as part of the  Vallis Clausa society,  (in Latin, “closed valley"). The Moulin de la Fontaine produces rag paper by hand, sheet by sheet.

Fontaine de Vaucluse

"Sorgue, your shoulders like an open book spread their reading"

Wrote the poet René Char.


When the paper mill technique passed from Italy to France, what was necessary for this industry to flourish? Essentially water, abundant and pure.

The Sorgue, a river praised by Petrarch, was an ideal site for the development of this formidable communication medium: paper

The first paper mill in Provence was established in Carpentras in 1374.

But Fontaine-de-Vaucluse, became the most important location for paper production.


In "Epistle to Posterity" Petrarch wrote:  "I met a very narrow but lonely and pleasant valley, called Vaucluse, a few miles from Avignon, where the queen of all the fountains, the Sorgue, takes its source. Seduced by the amenity of the place, I carried my books and my person. »
