Rhaetian Alps

The Rhaetian Alps extend across the high country of Graubünden and the adjoining lands of Tyrol and northern Italy. Their ranges include the Sesvenna Alps, whose peaks rise between eastern Switzerland, western Austria and northern Italy. Valleys cut through the mountain country on either side of the high ridges, while the Inn flows through the Engadine to the north. The mountains take their name from Raetia, a land brought under Roman rule in the age of Augustus.
