The Schönfeld castle in the Saxon village of Schönfeld was first mentioned in the 13th century and expanded over the centuries. The aristocratic Schönfeld family sat here until the early 15th century. The buildings date from the years 1560 to 1580. In 1882, Baron von Burgk acquired the Schönfeld Palace and had it rebuilt by 1884. Today Schönfeld Palace is one of the most important neo-renaissance castles in Saxony.
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.
