The Werdenfelser Land is a region of Upper Bavaria that extends from Mittenwald in the south to Farchant. It includes parts of the Bavarian Alps. From the Middle Ages until the Thirty Years' War, the Werdenfelser Land was subject to the Prince-Bishop of Freising, not the Duke of Bavaria.
The region derives its name from the medieval Werdenfels Castle north of Garmisch-Partenkirchen. The castle acted chiefly to secure the military and trade route that ran through the Loisach valley and linked trading posts in Italy and Upper Bavaria. It is sometimes called the Goldener Land after the wealth derived in the Middle Ages and Renaissance from the traffic along this Rottstraße, the main route over the Alps to Augsburg.
