Hohenwerfen Castle (Burg Hohenwerfen) stands high above the Austrian town of Werfen in the Salzach valley, approximately 40 km (25 mi) south of Salzburg.
The castle is surrounded by the Berchtesgaden Alps and the adjacent Tennengebirge mountain range. The fortification is a "sister" of Hohensalzburg Castle both dated from the 11th century.
Hohenwerfen was used as the castle 'Schloss Adler' in the 1968 film Where Eagles Dare.
