The Abbey of La Clarté-Dieu was a Cistercian monastery. The abbey was founded in 1239 by the executors of Peter des Roches, Bishop of Winchester, as one of a pair, the other being Netley Abbey in Hampshire, England. The bishop had conceived the idea of founding a pair of monasteries some years before and had begun collecting the necessary endowments for them, but his death in 1238 prevented him from completing the project. The first monks arrived at the site in 1240.
The abbey was severely damaged in the course of the Hundred Years War and the cost of rebuilding proved a heavy burden on the finances of the community. Nevertheless, La Clarté-Dieu managed to survive until the French Revolution when it was closed and sold off along with all the other monasteries of France. Following the revolution the abbey was for a long time used as a farm and some of the buildings were allowed to fall to ruin. Despite this, much of the mediaeval abbey remains in excellent condition along with some fine post-mediaeval additions. The abbey is preserved as an historic monument and is open to the public.
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.
