Rinkesta Castle is a castle at Eskilstuna Municipality in Södermanland. Rinkesta was withdrawn from the crown in 1594 through a change to Privy Councillor (Kammarråd) Gustaf Gabrielsson Oxenstierna (1551-1597). The main building was repaired after a fire in 1698. The current appearance was given to the castle during an extensive repair in 1775, during the ownership of Swedish Supreme Court marshal (Överstemarskalk) Thure Leonard Klinckowström (1735-1821) who acquired the estate in 1768.
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.
