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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
