This summer resort at the main crossroads of the Upper Salzach Valley sprang up around a castle. The castle was built in the 12th century and since then has been rebuilt many times, following its destruction during the Peasant Wars and numerous fires. Today it is the seat of the International Protestant Youth Community, a cultural centre and a hotel. The chapel (1533) features an interesting late-Gothic polyptych attributed to an Aussee Master. The Heiliger Leonhardkirche (Church of St Leonard), originally Gothic, was remodelled in the 18th century to a design by Johann Kleber. It contains a heavily ornamented Rococo pulpit and some remains of the old decorations, including an early 15th-century stone statue of Leonard. Mittersill lies at the Salzburg end of a beautiful mountain trail leading from East Tyrol, among the wild scenery of the Hohe Tauern National Park. The road known as Felberntauernstrasse affords lovely views of the rugged slopes of Grossvenediger.
