Preetz Priory is a former German Benedictine monastery of nuns founded in 1211 by Graf Albrecht of Orlamünde, nephew of King Valdemar II of Denmark. He founded it following a mystical experience which he later recounted happened while he was stalking a deer. After following it into a glen, the deer stood still and he suddenly saw a gleaming cross appear between its antlers. He felt that the site was a holy place which he called the Field of Mary and, to honor the vision, founded a monastery of nuns at a location some 4 km away. A monastery on the actual site of the vision was built only in 1260.
Suppressed in the 16th century due to the Protestant Reformation, it became an aristocratic Lutheran women's convent belonging to the Schleswig-Holstein knighthood. It continues in this capacity.
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.
