Schönburg Castle was first mentioned in history between the years 911 and 1166. From the 12th century, the Dukes of Schönburg ruled over the town of Oberwesel and had also the right to levy customs on the Rhine river. The most famous was Friedrich von Schönburg - a much-feared man known as “Marshall Schomberg” - who in the 17th century served as a colonel and as a general under the King of France in France and Portugal and later also for the Prussians and for William Prince of Orange in England.
The Schönburg line died out with the last heir, the son of Friedrich of Schönburg. The castle was burned down in 1689 by French soldiers during the Palatinate wars. It remained in ruins for 200 years until it was acquired by the German-American Rhinelander family who bought the castle from the town of Oberwesel in the late 19th century, and restored it.
The town council of Oberwesel acquired the castle back from the Rhinelander family in 1950. Since 1957 the Hüttl family have been living at the castle on a long-term lease; they operate a hotel and restaurant there.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.
