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 Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
