An attack by the Saracens in 891, who remained until the end of the 10th century, devastated the country around current Cannes. The insecurity of the Lérins islands forced the local monks to settle on the mainland, at the Suquet (today the old town). Construction of a castle in 1035 fortified the city by then known as Cannes.
The castle was damaged in end of the 16th century and partially demolished in the 18th century. In 1919, the municipality of Cannes acquired all the buildings in order to house its museum. Today the Musée de la Castre hosts 19th-century Riviera landscape art, musical instruments & ethnographical items in a medieval tower.
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.
