Sachsenburg Castle rises near Frankenberg, Saxony, on a rock over the Zschopau river. The castle complex, which was built in the early 13th century at the latest, was converted into a castle in the 1480s. The complex is one of the few examples of a completely preserved late Gothic residential palace in Saxony.
The Lords of Sachsenburg were mentioned for the first time in 1197. It is uncertain whether a castle already existed at that time. Around 1210/30, however, the existence of the castle can be reliably proven on the basis of archaeological finds. The builders were evidently the Lords of Mildenstein.
Since 1610 the castle served as an administrative building for the Electoral Saxon Office of Sachsenburg with Frankenberg. During the Thirty Years War , the first and second outer bailey were destroyed and the castle looted.
From 1864 the castle was used as custody for young female prisoners and in 1867 a penal and correctional institution was established here. The property was only reserved for prisoners until 1926, and from 1914 onwards there were prisoners of war (Russians, including interned academics and students of the Freiberg Mining Academy , Englishmen, Serbs).
Along with Lichtenburg, Sachsenburg was among the first concentration camps to be built by the Nazis, and operated by the SS from 1933 to 1937. The camp was an abandoned four-story textile mill which was renovated in May 1933 to serve as a 'protective custody' facility for dissidents such as Jehovah's Witnesses, who opposed the Nazi regime.
Today the castle restoration is in progress.
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.
