Burgruine Petersberg is a 9th-century castle ruin perched dramatically on a hilltop ridge above Friesach in Carinthia. Built from 1076 onward and originally owned by the Bishops of Salzburg, the fortress features a striking six-story keep with extensive architectural remains. The site now houses the Friesach City Museum, exhibiting exhibits about the town's history, culture, mining heritage, and medieval trade routes. Offering magnificent panoramic views over Friesach and the surrounding countryside, the ruins remain a favorite destination for hikers and history enthusiasts exploring Carinthia's rich architectural legacy.
