Geography of Switzerland rolling hills and plains of the plateau. The smaller Jura Mountains are located on the north west side of the plateau. Much of the northern border with Germany follows the Rhine, though the Rhine enters Switzerland near Schaffhausen. The eastern border with Germany and a portion of Austria is drawn through Lake Constance (). A portion of the southwest border with France is drawn through Lake Geneva. Switzerland is divided into 26 sovereign cantons. The cantons along the Swiss Plateau tend to be the most populous, industrial and religiously Protestant. The cantons in the Alps tend to be less populous,
Cantons of Switzerland until the late 15th century. "Ort" was increasingly replaced by "Stand" (plural: "Stände") "estate" about 1550, a term taken to imply liberty and sovereignty. Abolished in the Helvetic Republic, the term was revived in 1815 and remains in use today. The French term "canton" adopted into German after 1648, and then only in occasional use until the early 19th century: prominent usage of "Ort" and "Stand" gradually disappeared in German-speaking Switzerland from the time of the Helvetic Republic. Only with the Act of Mediation of 1803 did German "Kanton" become an official designation, retained in the Swiss Constitution of 1848.
