Hohensalzburg Fortress in the context of Salzburg, Austria

Salzburg is the fourth-largest city in Austria. In 2020 its population was 156,852. The city lies on the Salzach River, near the border with Germany and at the foot of the Alps mountains.

The town occupies the site of the Roman settlement of Iuvavum. Founded as an episcopal see in 696, it became a seat of the archbishop in 798. Its main sources of income were salt extraction, trade, as well as gold mining. The fortress of Hohensalzburg, one of the largest medieval fortresses in Europe, dates from the 11th century. In the 17th century, Salzburg became a centre of the Counter-Reformation, with monasteries and numerous Baroque churches built. Salzburg has an extensive cultural and educational history, being the birthplace of Wolfgang Amadeus Mozart and being home to three universities and a large student population. Today, along with Vienna and the Tyrol, Salzburg is one of Austria's most popular tourist destinations.

St Peter's Abbey (German: Stift Sankt Peter), or St Peter's Archabbey (German: Erzabtei Stift Sankt Peter, Latin: Archiabbatia sancti Petri Salisburgensis), is a Benedictine monastery and former cathedral in the Austrian city of Salzburg. It is considered one of the oldest monasteries in the German-speaking area, and in fact the oldest with a continuous history since its foundation in 696.

Festungsberg (Austrian German pronunciation: [ˈfɛstʊŋsbɛrɡ], lit. 'Fortress Mountain') is a mountain in the city of Salzburg in Austria, which rises to an elevation of 542 metres (1,778 ft). It is the site of the Hohensalzburg Fortress, which towers over Salzburg's historic city centre to the north, and forms part of the city's UNESCO World Heritage Site.

The Festungsberg forms the northern rim of the Berchtesgaden range within the Northern Limestone Alps.
