The original structure of Scharfenstein castle was built in 1250. It is suspected that the von Waldenburgs ordered its construction, but only its first owner occupant is known for certain. When, in the 15th century, Greifenstein Castle was destroyed, Scharfenstein also took over the guardianship of Thum, Ehrenfriedersdorf and Geyer. As a result, its value increased, so that in 1439 the Elector acquired the area from the Waldenburgs who were heavily indebted to him. On 26 January 1492 Henry of Einsiedel bought Scharfenstein Castle and its associated villages of Grießbach, Großolbersdorf, Grünau, Hohndorf Hopfgarten and Scharfenstein It remained in the family until 1931.
Following a fire during the night of 1st-2nd June 1921 the entire residential wing and part of the domestic wing was destroyed. From 1921 to 1923 the damaged wings were partially rebuilt to plans by Bodo Ebhardt, based on the old design.
In 1931, a factory owner, Captain Eulitz from Fährbrücke, acquires possession. By his efforts in 1932 in a bird observatory was established. Hundreds of nest boxes were put up throughout the 325 hectares of woodland on the estate; bird-ringing was carried out and scientific reports published, with the support of the Chemnitz Ornithological Society.
In 1945 this forest was seized and made public property, the castle was initially used as the mining school for the state-owned Wismut mining company and, in 1951, a special children's home was established here for maladjusted boys. In 1967, it was converted into a detention centre for juvenile delinquents. Ornithological work was undertaken by the museum at Augustusburg Castle.
In 1993 the castle was taken over by the Saxon Palace Department of the Free State of Saxony. In the period that followed the castle was renovated as a historic monument and converted into a museum. In 1995, on the completion of the renovation work, various exhibitions were opened - and for the first time since 1945, the castle was again open to the public. The bergfried is still used today as an observation tower.
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.
