Norderburg is a moated castle that was established in the 14th century. It was destroyed in 1514 during the Saxonian rebellion and rebuilt in 1534 by Hicko Kankena.
The castle's architecture is quite impressive with a beautiful facade, flanked by two lion statues at the entrance, an ornately designed Knight's Hall, and a spectacular great hall that features baroque paintings. The castle changed many owners and was also used as a private school, and later as a college. Since 1951, it is home to a middle school.
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.
