Thalasso de Lorient

Thalasso de Lorient in Morbihan, France, offers iodine-rich Atlantic thalassotherapy in the port city that hosts the Festival Interceltique de Lorient—the world's largest Celtic cultural festival, drawing over 800,000 visitors each August as the Breton, Irish, Scottish, Welsh, Cornish, Galician, and Asturian Celtic peoples converge for ten days of music, dance, and cultural celebration that makes Lorient the most internationally Celtic city in Europe for the duration of the festival. The iodine-rich Morbihan coastal waters used in the treatments reflect the exceptional marine environment of the Rade de Lorient and the mouth of the Blavet River, where tidal mixing creates a particularly mineral-rich marine water for therapeutic application. The Celtic Festival, the submarine base (France's largest functioning submarine base, whose bunkers are open to visitors as a remarkable piece of wartime industrial heritage), and the Atlantic thalassotherapy tradition create a Lorient experience of exceptional cultural, historical, and therapeutic maritime richness.
