The castle, or rather a fortified court in Candleston, was founded in the 14th century on the initiative of the Cantilupe family. It could have been built on the site of an earlier building from the 13th century. At the end of the fifteenth century, it was renovated and rebuilt by Mathew Cradock, a constable of castles in Caerphilly and Kenfig, and around 1500 transformations were made in the range of the great hall. Further modifications were carried out in the 17th century, when a new range was added next to the hall building. The lands of the estate in the Middle Ages were covered with sand from nearby dunes and lost their value, but the building remained inhabited until the 19th century. The last person living in the court was Sir John Nichol. When in 1808 he built a new residence, Candleston was sold and used by new owners as a farm. Eventually it was abandoned at the end of the 19th century and fell into disrepair.
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.
