Swedish conquerors established a sea fortress named Rågövik (“Rye Island Bay”) to the deep and wind-sheltered Paldiski Bay in the 17th century. Later it became a Russian naval base in the 18th century. Peter the Great planned to build a giant military port of there. The plan envisaged that the mole would offer shelter for the entire vast navy of Russia. Construction of the military port started in 1716. Despite the efforts of thousands of convicts, the planned 2-km-long giant facility could not be completed and even the completed part was quite soon destroyed by autumn storms.
In 1762, the Russians (Catherine II) renamed the sea fortress of Rogerwiek into Baltiyskiy Port (Baltic Port), and the Estonian pronounciation, Paldiski, became the official name in 1933. In 1962, Paldiski became a Soviet Navy nuclear submarine training centre. With two land-based nuclear reactors, and employing some 16,000 people, it was the largest such facility in the Soviet Union. Because of its importance, the whole city was closed off with barbed wire until the last Russian warship left in August 1994. Russia finally relinquished control of the nuclear reactor facilities in September 1995.

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.
