The Château de Mirabeau is a medieval castle overlooking the village of Mirabeau. Its origins date back to the 12th century, when it was first mentioned as a fortified structure. Initially owned by the Abbey of Saint-André, the castle underwent various changes over the centuries. The castle played a crucial role in the local economy, especially during the late Middle Ages, by controlling a key river crossing.
The current structure, likely built in the late 16th to early 17th century, features a quadrilateral layout with four circular towers. It has been remodeled and expanded, particularly in the 18th century, and includes a chapel and various living quarters.
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.
