Festungsberg

Festungsberg is a mountain in Salzburg municipality, Salzburg state, Austria. Its summit at about 542 m is the site of Hohensalzburg Fortress.

The mountain is located in the south of Salzburg's historic centre. It forms the northern rim of the Berchtesgaden range within the Northern Limestone Alps.

Archaeological findings date back to the Celtic La Tène culture. The area was fortified during the days of the Roman above the city of Iuvavum until King Odoacer of Italy commanded to leave the Province of Noricum in 488. About 715 Bishop Rupert of Salzburg established the Benedictine Nonnberg Abbey at the eastern foot of the mountain.
