Barsebäck Castle has existed in various versions at its present location since the 12th century. It received its current shape during a major renovation and rebuilding in 1889 and 1940. The current main structure is a three-story 19th-century reconstruction in Dutch Renaissance style, made to resemble the many original Renaissance castles still remaining in the Scanian landscape.
After the Scanian War, Barsebäck Castle was, along with all other castles owned by the Scanian noble family Thott, confiscated by the Swedish Crown, and thus became Crown property. In 1743, the castle was bought by the Swedish Colonel and Regimental Commander Gustaf David Hamilton, stationed in Malmö, an ancestor of the current owner.
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.
