Avanduse manor (Awandus) was first mentioned in 1494. The origins of the present-day building was a building that was erected in 1679-1684 by Tallinn master builder Gerd Vorberg at the initiative of the landowner at the time, Gideon von Fock. The building has however been heavily rebuilt since, with final changes being made by architect Rudolf von Engelhardt in 1890. Russian geographer Fyodor Litke is the most famous owner of the estate, and a plaque dedicated to his memory hangs from a wall of the manor.
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.
