It lies immediately below the summit of the Zugspitze at a height of 2,650 m and was opened on 20 June 1931. It used to house the top station of the Bavarian Zugspitze Railway as well as a tourist hotel. There was then a cable car from the Schneefernerhaus to the Zugspitze summit. In 1938 a gallery for pedestrians was opened from the ridge station of the Tyrolean Zugspitze Cable Car to the Schneefernerhaus. From 1945 to 1952 the hotel was commandeered for use as a "recreation facility" by the US Forces. [END]
