The first known owner of Sjöö castle was Peter Laurensson, mentioned in 1409. In 1541 the castle was bought by Jacob Vestgöte Sjöö and named after him. The present castle was built during the ownership of Johan Gabriel Stenbock. The castle was designed by Nicodemus Tessin the Elder and Mathias Spieler. The castle with its park is considered one of the most beautiful castles in Sweden with its perfect and harmonious proportions. In 1813 Sjöö castle was sold to Johan Gustav Baner, and it's still owned by the family Baner.
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.
