The Marsvinsholm estate was spoken about as Bosöe, Borsöe and Bordsyö in the beginning of the 12th century. By the middle of the 14th century it was owned by members of Ulfeld family. The possession were transferred to Otto Marsvin around 1630, who built the castle 1644-1648 and renamed it after himself. The name is derived from an Old Norse word for porpoise. The castle was in the beginning built on poles in a small lake. It forms a square in 4 floors and the northeast and southwest corners are provided with towers in five floors. 1782-1786 count Erik Ruuth made a thorough renovation. 1856-1857 baron Jules Sjöblad restored the castle.
Through succession and sales the castle has belonged to the families Thott, von Königsmarck, de la Gardie, Sjöblad, Ruuth, Piper, Tornerhielm and Wachtmeister. Count Carl Wachtmeister sold the castle and the remaining land to arl Jules Stjernblad in 1854. The castle was handed down to his daughter, the duchess Ida Eherensvärd. Her children, Rutger, Louise and Madeleine Bennet owned it until 1910 when it was sold to dame Johannes Jahennesen. 1938 it was handed down to his daughter, Anna Margrethe and her husband Iörgen Wedelboe-Larsen. Their son sold 1978 to Bengt Iacobaeus. His son Mr Tomas Iacobaeus is the current owner of Marsvineholm.
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.
