Karlsruhe Palace was erected in 1715 by Margrave Charles III William of Baden-Durlach, after a dispute with the citizens of his previous capital, Durlach. The city of Karlsruhe has since grown around it. The first building was constructed by Jakob Friedrich von Batzendorf. The city was planned with the tower of the palace at the centre and 32 streets radiating out from it like spokes on a wheel, or ribs on a folding fan.
Originally partially made of wood, the palace had to be rebuilt in 1746, using stone. Charles Frederick, Margrave of Baden-Durlach at the time, and who eventually became Charles Frederick, Grand Duke of Baden then had the palace altered by Balthasar Neumann and Friedrich von Kesslau until 1770, adding larger windows and doors, pavilions and wings. In 1785, Wilhelm Jeremias Müller shortened the tower, adding a cupola.
During the Revolutions of 1848, Leopold, Grand Duke of Baden was expelled in 1849 for some time. In 1918, the last monarch Frederick II, Grand Duke of Baden had to move out. The former residence of the Rulers of Baden is since used as Badisches Landesmuseum.
Much of the city centre, including the palace, was reduced to rubble by Allied bombing during World War II but was quickly rebuilt after the war.
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.
