The castle was never a permanent royal residence but primarily functioned as an administrative and defensive center for the Zähringen dukes.
The four corner towers were added to the original donjon in the early 17th century to provide a more representative appearance.
The Knight's Hall, or Rittersaal, dates back to the 12th century and is one of the best-preserved halls of its era in Europe.
The castle museum exhibits a significant collection of Thun majolica, a type of locally produced ceramic ware famous for its yellow and brown glazes.
The prison cells located in the towers were used until as recently as the 19th century.
Thun Castle is a 12th-century fortress situated on the Schlossberg hill overlooking the Aare River and Lake Thun. The central keep, known as the Donjon, was constructed by the Dukes of Zähringen and retains its original high-medieval structure. The building currently houses a historical museum featuring exhibits on regional culture, ceramics, and the castle's architectural evolution. Visitors can access the four corner towers, which offer panoramic views of the city, the surrounding Alps, and the Bernese Oberland. The Knight's Hall remains one of the few surviving ceremonial rooms from the Middle Ages in Switzerland. The castle serves as a cultural hub for the town of Thun, hosting various rotating exhibitions throughout the year.

Wear comfortable footwear, as the path from the town center involves a short but steep walk up cobblestone streets.
Combine your visit with a walk through the nearby Old Town (Altstadt) for historical architecture.
Don't rush only to the top floor; the museum exhibits on the lower levels provide essential context for the building's history.
The castle is closed during the winter months, typically reopening in early spring.
