Schloss Wickrath was built between 1746 and 1772 by count Wilhelm Otto Friedrich von Quadt. The Baroque palace was built to the foundations of late medieval water castle. The original castle was demolished in 1859 by the Prussian administration. The current ensemble of buildings in the park, the Baroque west and east wing and the so-called Landstallmeisterhaus, the residence of the former stud master were built in 1875. The park has the shape of a coronet of a count of the Holy Roman Empire.
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.
