Between its Gallo-Roman past and modernity, Lons-le-Saunier is a place where every stone tells a story, where the Jura region fully expresses itself through its natural and cultural riches. This richness invites discovery, inviting the curious and passionate to explore a heritage that combines ancestral know-how and dynamic contemporary life. Prehistoric and Gallo-Roman Origins of Lons-le-Saunier: An Economic Center Built on Salt
Located in a natural environment conducive to the exploitation of mineral resources, Lons-le-Saunier has been known since prehistoric times. The first traces of human activity date back to the Neolithic period, a clear testament to the early interest in this region of the Jura for its natural resources. Primarily, the presence of vast deposits of rock salt has driven economic activity since ancient times.
The Sequani, a Gallic people who dominated the region before the Roman conquest, took advantage of this wealth by developing extraction techniques and ensuring the salt trade. Salt, a valuable resource for food preservation and other uses, enabled Lons-le-Saunier to establish itself as a key trading center. The proximity of saltworks, such as those at Salins-les-Bains, reinforced this economic vocation.
With the Roman conquest, the town, then called Ledo Salinarius, underwent a more rigorous territorial structure. The establishment of the Roman baths testifies to the importance the Romans placed on thermal baths and the exploitation of salt water. These baths, integrated into the Gallo-Roman thermal network, served both for health care and as places of socialization. This practice would lay the foundations for a spa tradition that would continue for several centuries. 🔹 Rock salt mining since the Neolithic period
