Hohensalzburg Castle

Hohensalzburg Castle (German: Festung Hohensalzburg, literally "High Salzburg Fortress") sits atop the Festungsberg, a small hill in the Austrian city of Salzburg. Erected at the behest of the Prince-Archbishops of Salzburg with a length of 250 m (820 ft) and a width of 150 m (490 ft), it is one of the largest medieval castles in Europe. Hohensalzburg Castle is situated at an altitude of 506 m.

Construction of the fortress began in 1077 under Archbishop Gebhard von Helfenstein. This original design was just a basic bailey with a wooden wall. In the Holy Roman Empire, the archbishops of Salzburg were already powerful political figures and they expanded the castle to protect their interests. Gebhard's conflict with Emperor Henry IV during the Investiture Controversy influenced the expansion of the castle, with the Archbishop taking the side of Pope Gregory VII and the German anti-king Rudolf of Rheinfelden. The castle was gradually expanded during the following centuries. The ring walls and towers were built in 1462 under Prince-Archbishop Burkhard II von Weißpriach.

Prince-Archbishop Leonhard von Keutschach during his term from 1495 until 1519 further expanded the castle. His coadjutor Matthäus Lang von Wellenburg, who was later to succeed Leonhard, in 1515 wrote a description of the Reisszug, a very early and primitive funicular railway that provided freight access to the upper courtyard of the castle. The line still exists, albeit in updated form, and is probably the oldest operational railway in the world. The current external bastions, begun in the 16th century and completed in the 17th, were added as a precaution because of fears of Turkish Invasion.
