Schloss Elsum is a historic castle located in the Lower Rhine region of Germany. The castle was originally built in the 13th century as a fortified manor house, and it was later expanded and renovated over the centuries. The castle has a rectangular shape with four corner towers and a moat.
The interior of the castle features a variety of rooms, including a chapel, a great hall, and several bedrooms. The castle also has a wine cellar and a dungeon. In the 18th century, the castle was renovated in the Baroque style, and a new wing was added.
Elsum castle was mainly destroyed in 1945 during the Second World War and restored in the 1950s.
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.
