The Kasti estate was first mentioned in 1488, and it served as the vassal castle of von Uexkülls in the Middle Ages (parts have been preserved in the current main building).
Later on, the manor was associated with the noble families of von Baranoff, von Sivers and von Stackelberg. The manor house was rebuilt as a modern mansion round 1825, when the owner was count Sievers and when it became additional buildings with venice's windows. After burning in 1905 the former look was restorated. In 20. century the house became an office of Kolkhoz "Tasuja", also as cultural center and as shop. For the moment the house stands in private ownership.
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.
