Thermes Lédonia, Roman thermal baths in Lons-le-Saunier, France
The Thermes Lédonia occupies a nineteenth-century building within a seven-hectare park, featuring three distinct saline water sources for therapeutic treatments.
The thermal complex earned recognition as a historical monument in December 1999, preserving its architectural heritage and connection to Roman bathing traditions.
The facility continues the ancient practice of thermal treatments using mineral-rich waters containing over 300 grams of sodium chloride per liter.
Visitors can access various therapeutic treatments including hydrotherapy, balneotherapy, and specialized programs for rheumatology and dermatology conditions.
The thermal waters emerge at 17 degrees Celsius and contain therapeutic elements such as iron, copper, manganese, zinc, calcium, magnesium, and selenium.
