The keep of Crupet Castle was built in the 13th century and originally consisted of a square tower surrounded by a moat. The entrance was probably protected by a drawbridge and portcullis. In the 16th century, the keep was converted to a manor house. A corner tower was added, the windows were enlarged, and the timber top floor and roof were built. The drawbridge was probably also replaced at this time. The keep is not open for visits, but is highly visible from the surrounding roads.
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.
