The ruins of Streitburg Castle are the remains of a high mediaeval aristocratic castle above the village of Streitberg, in the market borough of Wiesenttal. They lie directly opposite the ruins of Neideck Castle, the symbol of Franconian Switzerland, on the other side of the valley. The ruins are freely accessible to the public.
The ruins of the spur castle are located at a height of 403.7 m above sea level on a rocky southwest-pointing hill, the Streitberg, above the eponymous village, which is bounded to the south and west by the Wiesent river and to the west by the valley of Schauertal.
Near the ruins of Streitburg are other former castles: to the northeast is the burgstall of Kulk on the hill named Guckhüll, to the southeast is Neideck Castle and the former motte castle of Wöhr which is on a former river island of the Wiesent near the hamlet of the same name. About 250 metres southwest and above the Neideck is the site of Wartleiten Castle, in the area of the present cemetery in Niederfellendorf is a castle site of the Fellendorfs and on the Hummerstein above Gasseldorf an early mediaeval burgstall.
References: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.
