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.

[1] The museum is open on Friday and Sunday from October until April.

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, while the second permanent exhibit focuses on the work of the famous puppeteer, Therese Keller (1923-1972).

She was a pioneer in the puppet theater in Switzerland.
