Rauenstein Castle guarded the crossing over the River Flöha along the road from Freiberg to Annaberg. The castle is first mentioned in 1323, although from archaeological investigations it is postulated that it had been built by around 1200. The first lords of Rauenstein were the Schellenbergers.
After several changes of ruler, the castle went into the possession of the Electorate of Saxony in 1567. The Amt of Rauenstein was given to Wolkenstein in 1596. Around 1630 large structural changes were made. The road tunnel also dates to this time.
From 1651 to 1743 the castle was rented to the von Römer family, who had become very wealthy as a result of silver mining in the Schneeberg area. Its owner, Christian August Hähnel, who had bought Rauenstein in 1816, his nephew, Wolfgang, Freiherr von Herder (owner from 1843 to 1853) and another family member, Wilhelm Freiherr von Herder, were members of the Saxon Landtag. The next owner, Gottfried Freiherr von Herder, was a German Conservative Reichstag MP from 1893 to 1898.
After its confiscation as part of the land reform in the Soviet Zone of Occupation in 1945, the castle was used as a children's convalescent home. It has been owned by a private family since 1998 and may now only be viewed from the outside.
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.
