The Salpa Line is a massive line of defensive fortifications approximately 1200 km long that was built in 1940-41 and in 1944 in order to defend the Eastern border of Finland.
The Salpa Line Museum in Miehikkälä is a museum on military history established in 1987 displaying the history of fortification works of the Salpa Line. The permanent exhibition of the museum consists of the exhibition and multimedia shows at the museum cafeteria and of guided tours to the fortifications on the outdoor museum area.
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.
