Overview
The Rhaetian Alps are a mountain range of the Eastern Alps. The SOIUSA classification system divides them into the Western 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 name relates to a Roman province and the Rhaetian people subdued under Emperor Augustus in 15 BC.
