The Festungsbahn is a funicular railway providing access to Hohensalzburg Fortress in Salzburg municipality in Austria.

The Festungsbahn opened in 1892, and should not be confused with the much older Reisszug line that provides goods access to the castle.

[4] The Festungsbahn opened in 1892 as a water balance funicular operated by the Salzburger Eisenbahn- und Tramwaygesellschaft.

Previously used as barracks, the line made the fortress available to a broader range of visitors.

[5][6] Between January and April 2011, the funicular was again modernized, at a cost of €4 million.
