The Roosna-Alliku Manor was donated to von Rosen family in 1620 by Christina, Queen of Sweden. The coat of arms of family features a white rose, which has become the symbol of the manor. In 1721 it was acquired by von Stackelbergs. The present main building is one of the most impressive examples of early classical manor architecture in Estonia, completed by Otto Friedrich von Stackelberg in 1786. Worthiest of attention in the interior are the two rooms with artificial marble walls. The manor building has been a school since 1924. Visits during the school period are possible by appointment only.

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.
