Hohenwerfen Castle

Hohenwerfen Castle (German: Festung Hohenwerfen, lit. 'Hohenwerfen Fortress') is a medieval rock castle, situated on a 623-metre (2,044 ft) precipice overlooking the Austrian market town of Werfen in the Salzach valley, approximately 40 kilometres (25 mi) south of Salzburg. The fortress is surrounded by the Berchtesgaden Alps and the adjacent Tennen Mountains. Hohenwerfen is a "sister" of Hohensalzburg Fortress, both built by the Archbishops of Salzburg in the 11th century.
