Celles-sur-Belle royal abbey was founded in 1137. It was rebuilt in the 15th century and destroyed by Huguenots in 1568. The current abbey was reconstructed between 1660 and 1685 on the orders of Louis XIV.
Overlooking both the Belle Valley and beautiful French-style gardens, the majestic 17th-century convent buildings in the Louis XIV style house a museum where you can see the Abbot's room, a recreated monk's cell, and collections of religious objects and ecclesiastical clothing.
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.
