Amlishagen Castle was built in the 13th Century and first mentioned in 1253. In the second half of the 14th Century, 1601 and in the 19th Century the castle was expanded and renovated. The castle was owned by the Lords of Amlingshagen and later by the Lords of Wollmershausen. The castle is currently privately owned and occupied.
After the family von Wollmershausen died out in the 18th Century, the castle was owned by a number of individuals. The castle was finally bought by Gebhard Leberecht von Blücher the Prussian Generalfeldmarschall who led his army against Napoleon I at the Battle of the Nations at Leipzig in 1813 and at the Battle of Waterloo in 1815 with the Duke of Wellington. A distant descendant owns the castle today.

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.
