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 Externsteine (Extern stones) is a distinctive sandstone rock formation located in the Teutoburg Forest, near the town of Horn-Bad Meinberg. The formation is a tor consisting of several tall, narrow columns of rock which rise abruptly from the surrounding wooded hills. Archaeological excavations have yielded some Upper Paleolithic stone tools dating to about 10,700 BC from 9,600 BC.
In a popular tradition going back to an idea proposed to Hermann Hamelmann in 1564, the Externsteine are identified as a sacred site of the pagan Saxons, and the location of the Irminsul (sacral pillar-like object in German paganism) idol reportedly destroyed by Charlemagne; there is however no archaeological evidence that would confirm the site's use during the relevant period.
The stones were used as the site of a hermitage in the Middle Ages, and by at least the high medieval period were the site of a Christian chapel. The Externsteine relief is a medieval depiction of the Descent from the Cross. It remains controversial whether the site was already used for Christian worship in the 8th to early 10th centuries.
The Externsteine gained prominence when Völkisch and nationalistic scholars took an interest in the late 19th and early 20th centuries. This interest peaked under the Nazi regime, when the Externsteine became a focus of nazi propaganda. Today, they remain a popular tourist destination and also continue to attract Neo-Pagans and Neo-Nazis.
