The history of Kyminkartano estate starts around 1350, when Earl Erengisle Suneson acquired some farms around the branches of Kymijoki river. He donated the estate in 1370 to Seneschal Bo Jonsson Grip, who was one of the most powerful noblemen of the kingdom. Late Grip donated Kyminkartano to Vadstena Abbey.
King Gustav Vasa visited in Kyminkartano in 1555 and acquired it to the Crown. After Russia had conquered the area in the 18th century, the government redeemed most of the estate's property. The new main building was built in the 1790s and owned by Wrangel, Clayhills, Bruun and Naht families. Today Kyminkartano is privately owned and not 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.
