Schloss Wickrath was built between 1746 and 1772 by count Wilhelm Otto Friedrich von Quadt. The Baroque palace was built to the foundations of late medieval water castle. The original castle was demolished in 1859 by the Prussian administration. The current ensemble of buildings in the park, the Baroque west and east wing and the so-called Landstallmeisterhaus, the residence of the former stud master were built in 1875. The park has the shape of a coronet of a count of the Holy Roman Empire.
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.
