Rhone in the context of "Principality of Orange"

The Canton of Geneva, officially the Republic and Canton of Geneva, is one of the 26 cantons of the Swiss Confederation. It is composed of forty-five municipalities, and the seat of the government and parliament is in the city of Geneva.

Geneva is the French-speaking westernmost canton of Switzerland. It lies at the western end of Lake Geneva and on both sides of the Rhone, its main river. Within the country, the canton borders Vaud to the east, the only adjacent canton. However, most of Geneva's border is with France, specifically the region of Auvergne-Rhône-Alpes. As is the case in several other Swiss cantons (Ticino, Neuchâtel, and Jura), Geneva is referred to as a republic within the Swiss Confederation.

Gallia Narbonensis (Latin for "Gaul of Narbonne", from its chief settlement) was a Roman province located in Occitania and Provence, in Southern France. It was also known as Provincia Nostra ("Our Province"), because it was the first Roman province north of the Alps, and as Gallia Transalpina ("Transalpine Gaul"), distinguishing it from Cisalpine Gaul in Northern Italy. It became a Roman province in the late 2nd century BC. Gallia Narbonensis was bordered by the Pyrenees Mountains on the west, the Cévennes to the north, the Alps on the east, and the Gulf of Lion on the south; the province included the majority of the Rhone catchment. The western region of Gallia Narbonensis was known as Septimania. The province was a valuable part of the Roman Empire, owing to the Greek colony and later Roman Civitas of Massalia, its location between the Spanish provinces and Rome, and its financial output.

The Western Alps are the western part of the Alpine Range including the southeastern part of France (e.g. Savoie), the whole of Monaco, the northwestern part of Italy (i.e. Piedmont and the Aosta Valley) and the southwestern part of Switzerland (e.g. Valais). In the southeast the range is bounded by the Italian Padan Plain. In the west, the valley of the Rhone river separates it from the Massif Central. The northernmost part of the Western Alps - in the wide meaning of the term - is formed by the Swiss Prealps Sub-Range.

The peaks and mountain passes are higher compared to the Eastern Alps, while the range itself is not so broad and more arched.

The Alpine foothills, or Prealps (German: Voralpen; French: Préalpes; Italian: Prealpi; Slovene: Predalpe), may refer generally to any foothills at the base of the Alps in Europe. They are the transition zone between the High Alps and the Swiss Plateau and the Bavarian Alpine Foreland in the north, as well as to the Pannonian Basin (Alpokalja) in the east, the Padan Plain in the south and the Rhone Valley in the west.

Walser German (German: Walserdeutsch) and Walliser German (Walliserdeutsch, locally Wallisertiitsch) are a group of Highest Alemannic dialects spoken in parts of Switzerland (Valais, Ticino, Grisons), Italy (Piedmont, Aosta Valley), Liechtenstein (Triesenberg, Planken), and Austria (Vorarlberg).

Usage of the terms Walser and Walliser has come to reflect a difference of geography, rather than language. The term Walser refers to those speakers whose ancestors migrated into other Alpine valleys in medieval times, whereas Walliser refers only to a speaker from Upper Valais – that is, the upper Rhone valley. In a series of migrations during the Late Middle Ages, people migrated out of the Upper Valais, across the higher valleys of the Alps.

This article contains a sortable table listing all major lakes of Switzerland. The table includes all still water bodies located either entirely or partly in Switzerland, both natural and artificial, that have a surface area of at least 30 hectares (74 acres), regardless of water volume, maximum depth or other metric. These lakes are ranked by area, the table including also the elevation above sea level and maximum depth. They are either natural (type N), natural but used as reservoirs (NR) or fully artificial (A).

Along with the mountains, lakes constitute a major natural feature of Switzerland, with over 1,000 km (620 mi) of shores within the country. Lakes, large and small, can be found in almost all cantons and provide an important source of water, leisure opportunities, as well as suitable habitat for fish-eating birds. The two most extensive, Lake Geneva and Lake Constance, are amongst the largest in Europe and mark the border of the Swiss Plateau, along with the Alps and the Jura Mountains. The largest wholly Swiss lake is Lake Neuchâtel. The remaining lakes over 100 km (39 sq mi) are Lake Maggiore and Lake Lucerne. In total 103 lakes exist that are more than 30 ha (74 acres) in surface area, and a considerable number of smaller lakes. All these lakes are found in the four major river basins of Switzerland: Rhine, Rhone, Po and Danube, at almost all elevations below the permanent snow line.
