evidence: Bordered by three countries, Lake Constance occupies an extremely beautiful corner of Central Europe - and is an ideal destination for a relaxing short break or longer family holiday. The 270km shoreline is shared between Germany, Austria and Switzerland. The lake is essentially a bulge in the Rhine - mirroring Lake Geneva, an expansion of the Rhône, at the other end of Switzerland. [...] More than half of the shoreline of Lake Constance is in Germany. There are three distinct areas. The German stretch on the north shore, between Bregenz in Austria and the town of Konstanz and the Swiss border, is known as Obersee; Uberlingen, the north-western arm; and Untersee, the "lower lake" in the south-west. The views from the German shore across to the Swiss Alps are stunning. [...] You might also hear the expression "Swabian Sea". The southern part of Germany adjoining Lake Constance is the ancient region of Swabia. German is the language of choice around the lake and on related websites; few concessions are made to speakers of other languages.
