Salzburg City Walls
The city walls of Salzburg were (or still are) a sophisticated system developed over the course of centuries. Three major building periods were supplemented with a consistent extension and development, which often took advantage of natural barriers such as the River Salzach or the Stadtberge (City Hills). We have written several articles on certain segments or individual bastions, towers and gates (let along the Fortress Hohensalzburg). In this set of three articles, we try to give an overview on the city walls divided into the three main construction periods.
Three Period of Fortifying Salzburg
The Medieval "Erste Stadtbefestigung" (mainly 13th century); the "Zweite Stadtbefestigung" from the late Middle Ages (late 15th century); and finally the "Dritte Stadtbefestigung" of which most remains today (built in the 17th century).
The city walls make a nice theme to explore parts of the Old Town that you would not notice otherwise. There are "hidden" towers such as those at the Richterhöhe; there are good examples for technological progress (if you walk along the main ridge of the Mönchsberg, you will get from the Medieval Bürgerwehr to the 17th century Müllner Schanze). There are examples for extensions and adaptations (such as the Kapuzinerkloster, which was built on the foundations of a Medieval castle); but also examples where city walls and towers were incorporated into ordinary building (for example in the Griesgasse) or demolished (such as the Michaelitor).
