Klempenow Castle was built during the time of German settlement in Pomerania in the 13th century and formed part of a series of fortifications on the border with Mecklenburg. The original castle consisted of two towers and a three metre thick defensive wall. It has been substantially altered during the centuries.
During the 17th century it acquired more or less the present shape and look. When Pomerania was ruled by Sweden, the castle was given as a fief to Dodo zu Innhausen und Knyphausen by the Swedish king. From 1762, it belonged to the Swedish Crown. It has since housed several different residents; after World War II, it housed refugees expelled from former German lands and at one time as many as fourteen families lived in the castle. After 1990, a renovation of the castle was carried out.
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.
