Thermal Station and Spa

In the southwest of France in the very heart of Gascony (Gers),  the Thermal Spa resort of Castéra-Verduzan is located between Bordeaux and Toulouse.


A bit of history:

It is likely that the Romans already knew and utilized the Thermal Springs of Castéra-Verduzan: "La Petite et Grande Fontaine" ("The small and big fountain"). Roman camps had probably settled near the source. Castéra comes from the Latin name "Castra" which means "Camp".

The idea of using water for localized treatments on the mucous membranes comes from an ancestral practice. Since immemorial time, the inhabitants of the village of Castéra-Verduzan went the source when they suffered from sore throats in order to use the water to gargle and mouthwash. The soothing benefits of this water were reknowned.

The first Thermal Spa establishment was built by Le Marquis de Pins on the site of the Thermal source called the "Grande Fontaine". Slowly and steadily, the number of visitors continued to grow until the end of the last century as the unique benefits became well known to more people.
