Wittigkofen Castle was originally built as a residence for a farm and was awarded to the followers of the Zähringians. In the mid-13th century Heinricus Wittenchoven managed the farm. He was a member of the council and the first documented feudal superior. The property was also home to the monastery of Interlaken. The castle had several owners and belonged to different families. Beat Ludwig von Mülinen (1521-1597) purchased the castle in 1570 and gave half to Hans Rudolf Steiger (1549-1577) six years later.
In June 2011 a decision was made by the director Jürg StüssiLauterburg of the Library am Guisanplatz (BiG), a federal military library in Bern, to purchase a historical collection of items from the Von Wurstemberger family. The collection of items had been collected and exhibited in the Wittigkofen Castle. 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.
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.
