Broich Castle was originally erected to protect the town of Mülheim from invasion by the the Normans in the late 9th century. It is probably the oldest, still maintained Carolingian fortification in German-speaking Europe.
The abandoned castle was rebuilt and expanded by the noblemen of Broich in the end of the 11th century. The castle survived a long and eventful history, including bloody feuds, wars, occupation and destruction.
Over 200 years ago, Broich’s most famous guest stayed there - Luise, Queen of Prussia - as the castle was owned by her grandmother.
Today, an exhibition of the local society for history informs the visitor about these events and explains their meaning for the city Mülheim an der Ruhr. It is also a popular location for weddings, music festivals and other events.
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.
