Laiuse Castle was the first castle in Estonia built to cope with firearms. The oldest part of the castle was probably built in the end of 14th century by the Livonian Order. It was first mentioned in 1406. In 1558 during the Livonian War the castle was conquered by Russian troops and badly damaged. Nonetheless the castle was later still in use both by Polish and Swedish rulers. During the Great Northern War, from 1700 to1701, after the Battle of Narva, the Swedish king Charles XII established his winter quarters here. For five months Laiuse was the administrative center of Swedish Empire.
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.
