An important natural product is extracted from the sea's saltwater here. Only through the power of the elements, sun and wind, which evaporate the water in the saltworks' shallow basins, does pure salt remain. Even today, you won't find a kitchen without salt to season dishes. But in earlier times, it had an additional significance: It was important for preserving food—making it so precious that salt was called "white gold."
