Blankenhain Castle is a large castle in Blankenhain near Crimmitschau. The castle dates back to the 12th century. It is first documented in 1423 as Wasserburg. Half of it burned down in 1661 and was rebuilt in 1699 (some sources say 1700). In 1765 the castle acquired its current Baroque appearance with mansard roof and domed towers. After World War II, the Soviet regime ordered the castle destroyed, but it was saved by the intervention of courageous locals. Since 1981, the castle and the surrounding land have been developed as an open-air museum of agriculture and rural life in central Germany between 1890 and 1990. The museum covers 11 hectares, including 60 buildings.
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.
