Lamprechtsburg castle consists of a simple Palas, keep, farm buildings and chapel. It is surrounded by the curtain wall. The chapel is mentioned in 1075 or 1090 and the wooden fort was replaced by stone castle in 1225 by the lords of Lamprechtsburg.
In the 1570s extensive restoration work was carried out. In 1812, the estate was sold to the priest Joseph Hauptmann, whose descendants are still the castle owners.
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.
