Liikkala fort was built by Russians in 1791-1792 as part of the South-Eastern Finland fortification system. It was meant to defend the road from the Swedish border to Hamina, which the Swedish army had used to attack Hamina in the Russo-Swedish war in 1788. Liikkala contained two ground redoubts and four demi-bastions.
After the Finnish War (1808-1809) Liikkala was abandoned, because the border was moved far away to west. Restoration of Liikkala Fort has been in progress since 1980 as an employment project by the National Board of Antiquities and the Ministry of Labour. Nowadays there remains well-preserved ground walls and some ruins of the Russian barracks.
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.
