Beat Ludwig von Mülinen (1521-1597) purchased the castle in 1570 and gave half to Hans Rudolf Steiger (1549-1577) six years later.

The collection included a large library, maps, and a portrait of Johann Ludwig Von Wurstemberger, a cabinet, and drawings.

The Von Wurstemberger library was located in the French room of the castle and contained many books that reflected the impact that this family had on the Confederation's military history.

Before being packed for transfer, every book was thoroughly cleaned with a special vacuum to avoid bringing insects to their new location.

The books were packed into 50 removal boxes for transfer to the Library am Guisanplatz, with the help of active military personnel, and moved to their new location in September 2011.
