By the 12th century a castle was built in Münsingen town from which the Senn family ruled the town. However, it was demolished by Bern in 1311. A wooden outbuilding was built on the castle lands three years later, which later became the cantonal psychiatric clinic. In 1550 the Schultheiss Hans Franz Nägeli rebuilt the castle building into its current appearance. It was renovated and repaired in 1749–53. In 1977 the municipality acquired the castle and converted it into a municipal museum.
The museum is open Friday and Sunday from October until April. It contains two permanent exhibits as well as occasional temporary exhibits. The first permanent exhibit focuses on the history of the town and on the Steiger family who lived in the castle for almost three centuries. The second permanent exhibit focuses on the work of the famous puppeteer, Therese Keller (1923-1972) who was a pioneer in the puppet theater in Switzerland.References:
The Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
