Wiesentfels castle belonged from 1333 to 1938 to the Counts of Giech, who received it from the Prince-Bishopric of Bamberg. After the Hussite Wars the castle was rebuilt (from 1476 to 1481). In 1525, it was burnt down by rebellious peasants and rebuilt in the old style by Count Achaz von Giech.
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.
