Mittersill Castle, Medieval castle hotel in Salzburg, Austria

Mittersill Castle is a stone fortification positioned on a hillside above Salzach Valley, offering views toward the Kitzbühel Alps and Hohe Tauern National Park. The building has been converted into a hotel with ten suites, a spa center, an outdoor pool, and restaurants serving regional cuisine.

The castle was founded in 1150 by the Counts of Lechsgemünd and served as an administrative center for the Archbishopric of Salzburg beginning in 1228. This role continued until the early 1800s.

The castle's name comes from the Counts of Mittersill, who took it around 1180 after earlier calling themselves Counts of Lechsgemünd and Sulzau. From 1228 it housed the archbishops' administrators and a regional court, where witch trials were held from the 16th into the 18th century. Since 1967 it has served as a Christian student conference centre, and since 2010 a restaurant has operated in it.

The property sits on a hillside with sloped pathways, so visitors should expect uneven terrain and wear comfortable shoes. The location offers good access to the valley regions and makes it easy to explore the surrounding landscape.

After the war, when the owners recovered the confiscated castle, they found thousands of skulls of Asiatic origin in all its rooms, left behind by the Nazi "Ahnenerbe" institute for Inner Asia research that had occupied the building.
