Neuenstein Castle origins date from the 13th century when it was a residence of Neuenstein and Hohenlohe counts. It was remodelled in the 16th century in the Renaissance style. Since 1878 the castle has hosted Hohenlohe family museum, which is one of the oldest private museums in Germany. The museum has for example an intact late medieval kitchen.
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.
