Šternberk Castle was mentioned first time in 1269 and it was built decaces earlier. It was later altered in Renaissance style but suffered damages in Thirty Years War.
Around the year 1700 the estate was bought by Jan Adam Ondřej of Lichtenštejn. The Lichtenštejns owned the castle till the end of the World War II and also realized the last big reconstruction. The reconstruction did not only give the castle todays appearance, but also the first floor was opened for public as a museum due to it. Lichtenštejns lived on the second floor, but only till the end of the World War II.
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.
