The Royal Abbey of Notre-Dame de Lieu-Dieu, founded in 1197 by Richard the Lionheart for Premonstratensian canons, suffered three devastations in 1372, 1484, and 1568. After various trials, it was annexed to a Parisian Premonstratensian college in 1720. The abbey was turned into an agricultural enterprise in 1733 and sold as a national asset in 1791. In 2012, it was acquired and restored by Mr. and Mrs. Alain du Peloux, opening to visitors in 2013.
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.
