Canton of Graubünden in the context of "Furka Oberalp Railway"

The Rhine (/raɪn/ RYNE) is one of the major rivers of Europe. The river begins in the Swiss canton of Graubünden in the southeastern Swiss Alps. It forms part of the Swiss-Liechtenstein border, then part of the Swiss-Austrian border. From Lake Constance downstream, it forms part of the Swiss-German border. After that the Rhine defines much of the Franco-German border. It then flows in a mostly northerly direction through the German Rhineland. Finally, the Rhine turns to flow predominantly west to enter the Netherlands, eventually emptying into the North Sea. It drains an area of 185,000 km.

Its name derives from the Gaulish Rēnos. There are two German states named after the river, North Rhine-Westphalia and Rhineland-Palatinate, in addition to several districts (e.g. Rhein-Sieg). The departments of Bas-Rhin and Haut-Rhin in Alsace (France) are also named after the river. Some adjacent towns are named after it, such as Rheinau, Stein am Rhein, Rheineck, Rheinfelden (Switzerland) and Rheinfelden (Germany).

Districts of Switzerland are a political subdivision for cantons. In the federally constituted Switzerland, each canton is completely free to decide its own internal organisation. Therefore, there exists a variety of structures and terminology for the subnational entities between canton and municipality, loosely termed districts. Most cantons are divided into Bezirke (German for districts, singular Bezirk). They are also termed Ämter (Lucerne, singular Amt), Amtsbezirke (Bern, Amtsbezirk), district (in French) or distretto (Ticino and part of Graubünden). The Bezirke generally provide only administration and court organization. However, for historical reasons districts in cantons Grisons and Schwyz are their own legal entities with jurisdiction over tax and often have their own Landsgemeinde.

Seven of the 26 cantons – Uri, Obwalden, Nidwalden, Glarus, Zug, Basel-City and Geneva – have always existed without the district level of government. An eighth one, Appenzell Innerrhoden, uses no intermediate level either, but calls its lowest-level subdivisions Bezirke, although they are functionally equivalent to municipalities elsewhere.

Sutsilvan (Rumantsch Grischun: sutsilvan; Vallader: suotsilvan; Putèr: suotsilvaun; derived from sut "below" and selva "forest") is a dialect of the Romansh language spoken in Domleschg, Heinzenberg, Schams, and Val Ferrera, Canton of Graubünden, Switzerland.

Since 1601 it has a written form: a cathecismus for school use. There is an individual dictionary for this dialect.

The Rhaetian Alps (Italian: Alpi Retiche; German: Rätische Alpen) are a mountain range of the Eastern Alps. The SOIUSA classification system divides them into the Western, Southern Rhaetian Alps and Eastern Rhaetian Alps, while the Alpine Club classification of the Eastern Alps places most of the Rhaetian subranges within the Western Limestone Alps.

They are located along the Italian–Swiss and Austrian–Swiss borders, in the canton of Graubünden in eastern Switzerland; in the state of Tyrol in Austria; and in the Italian regions of Trentino-Alto Adige and Lombardy.

The Landwasser is a 30.5-kilometre (19.0 mi) river in canton of Graubünden, Switzerland. Its origin was Lake Davos before this was turned into a reservoir for a power station. Nowadays it is prolonged by the creek Flüelabach at its source and changes its name near Davos Dorf. The town of Davos is the largest, uppermost, and, except for the last bit, the only larger settlement on the river. Landwasser empties into the Albula below the village of Filisur.
