Merode estate was first time mentioned in 1170 and it was originally built by ministrial Werner from Kerpen. The first mention of castle dates from 1263. The current appearance was created mainly by Marshal Jean Philippe Eugène de Merode-Westerloo in the early 18th century. It was partially destroyed during the Second World War and rebuilt. The another big fire in 2000 destroyed 80% of interior and the restoration is still going on. The garden is used for events.
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.
