Neurathen Castle (Felsenburg Neurathen), which was first mentioned by this name in 1755, is located near the famous Bastei rocks near Rathen in Saxon Switzerland. This was once the largest rock castles in the region, but today only the rooms carved out of the rock, passages, the cistern and rebates for the timber of the former wooden superstructure have survived. In the years 1982–1984 parts of the extensive castle were used to build the open-air museum.
The beginnings of Neurathen date back to the first half of the 13th century, however the site may have been inhabitated already in the Bronze Ages. The castle was inherited and sold, repeatedly besieged, conquered and burned in the wars between Bohemian and Saxonian armies. In 1485 it fell to the Duke Albrecht, but he never restored it and the castle eventually collapsed. During the Thirty Years' War, his ruins served to shelter the inhabitants of Pirna before the Swedes.
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.
