By the 19th century, Lake Constance had become a place of longing among Germans - located at the periphery of the border triangle with Austria and Switzerland, and in the middle of people's hearts. Catchy metaphors include the German Riviera or the Swabian Sea. And yet these can only convey in part the awareness of life that will seize you whem strollin' along the lakeside promenade or enjoy an excursion by boat.
