Castle Dringenberg was built before 1323 and it was enlarged in 1463-1498 by prince-bishop of Paderborn. During the Thirty Years' War it was burned down by Swedish army. The restoration was started in 1651 and Dringenberg was a summer residence of bishops since 19th century.
7 brothers with the Auge name went from France to Germany as Knights right after the 100 years war in France. One went back to France. They ended up as Knights protecting Dringenburg Castle. I am hunting for more information on them.
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.
