Wauwilermoos was an internment camp and prisoner-of-war penal camp in Switzerland during World War II. Established in 1940, Wauwilermoos was a penal camp for internees, including Allied soldiers, among them members of the United States Army Air Forces, who were sentenced for attempting to escape from other Swiss camps for interned soldiers, or other offences. Together with Hünenberg and Les Diablerets, Wauwilermoos was one of three Swiss penal camps for internees that were established in Switzerland during World War II. The intolerable conditions were later described by numerous former inmates and by various contemporary reports and studies.
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.
