HISTOIRE
2,000 Years of History
The salt marshes of Guérande are among the oldest salt-producing sites in Europe, with roots reaching back to Roman times.
Through crisis after crisis, they have been safeguarded and passed down by the hands of the salt workers themselves.
3rd century onward
Salt-making in Roman times
Salt-making on the Guérande peninsula dates back to around the 3rd century. Drawing Atlantic seawater inland and crystallizing it with nothing but the sun and the wind, this traditional method has been practiced since the days of the Roman Empire. By the Middle Ages, salt had become one of Brittany's most important trade goods — known as "white gold."
1840
The peak — 2,600 hectares of salt marshes
In the mid-19th century, the marshes of Guérande stretched across roughly 2,600 hectares, with several thousand paludiers working the salt. They flourished as one of France's largest producers of sun-dried sea salt.
1960–70s
A fight for survival
With the rise of industrially refined salt and the spread of coastal resort development, marsh after marsh faced the threat of being filled in. Traditional salt-making stood at the brink of extinction. The number of paludiers plummeted, and the marshes fell into disrepair.
1972
The salt workers unite
To meet the crisis head-on, the remaining paludiers banded together to form a producers' group. Driven by a fierce resolve to "protect the marshes with our own hands," they laid the foundation of what would become the cooperative — the very beginning of Le Guérandais.
1988
Becoming an agricultural cooperative
The producers' group was formally incorporated as an agricultural cooperative. Each paludier is a member with a voice in how the cooperative is run — a democratic structure that endures to this day. The guiding ideal, "an organization of salt workers, by salt workers," has never changed.
1989
Nature & Progrès certification
The cooperative earned France's most rigorous natural-food certification — formal recognition that its salt is made with no chemical treatment and zero additives.
1991
Label Rouge — France's highest quality mark
Fleur de sel (the "flower of salt") was awarded the Label Rouge (Red Label), France's official mark of the highest quality — the first time the distinction had ever been granted to a salt.
1994
Terre de Sel opens
The cooperative opened a visitor center where guests can explore the marshes. More than 70,000 people visit each year to experience the work of the paludiers and the ecosystem of the salt marshes up close.
1997
Full independence
Breaking free of the major food corporations, the cooperative established a structure in which production, processing, and sales are all managed by the paludiers themselves.
2012
IGP (Protected Geographical Indication)
The salt was granted the EU's Protected Geographical Indication (Indication Géographique Protégée). The name "Guérande" is now legally reserved for salt produced in this region by traditional methods.
2024
PME+ certification — a sustainable small business
The cooperative earned the PME+ label, which recognizes environmental care, social responsibility, and sustainable management. Today it stands as France's No. 2 domestic brand and exports to more than 55 countries.
