Étang de Thau, Mediterranean lagoon in Sète, France
The Étang de Thau extends over 7,500 hectares with a length of 21 kilometers and connects to both the Mediterranean Sea and Canal du Midi.
Ancient civilizations, including Greeks and Romans, established settlements around the lagoon to extract salt and develop maritime trade routes.
Local fishermen maintain traditional methods of oyster and mussel cultivation, producing 13,000 tonnes of shellfish annually from 2,750 designated farming tables.
The northern shores contain multiple fishing villages offering fresh seafood, while water temperatures range from 3°C to 29°C throughout the seasons.
The lagoon forms the largest saltwater basin along the French Mediterranean coast, reaching depths of 30 meters in certain areas.
