Ruine Karlstein, Castle ruin in Bad Reichenhall, Germany.
Ruine Karlstein comprises the stone remains of a fortress situated high on Pankrazfelsen peak above Bad Reichenhall. The location overlooks the road to Thumsee lake within the mountainous Berchtesgadener Land landscape.
Founded in 1150 by Konrad von Peilstein, the fortress came under Bavarian ducal rule in 1218. It later served as a residence for wealthy Reichenhall citizens.
The name comes from a medieval military leader called Karl, and the nearby Pankrazkirche remains an active pilgrimage church today. This religious site shows how closely the castle was connected to the spiritual life of the region.
Multiple hiking trails of varying difficulty lead to the ruins, with the Pankraz-Kircherl loop from Weißbach offering a comfortable route. The climb is manageable and the site is easily accessible on foot.
The experience of visiting the ruins is shaped by the nearby pilgrimage church that remains in use today. This combination of medieval military architecture and active religious life creates an unusual destination.
