The people of Savonlinna had to go to the Sääminki church when they didn't have their own church. In 1850 governor Aleksander Thesleff gave order to build a church in Savonniemi. The actual construction began in 1874 and was completed in 1878. The church was designed by architect Axel Hampus Dahlström in the Gothic Revival style and it has room for 1000 people.
In 1896 the new diocese of Savonlinna was founded and the Savonlinna church became a cathedral. The first bishop was Gustaf Johansson. In 1925 the bishop's seat was moved to Vyborg, but the church still retained "cathedral" as its name.
During the Winter War in 1 May 1940 Savonlinna was bombed and the church was damaged. It was restored in 1947–1948 by architect Bertel Liljeqvist. In 1990–1991 it was renovated by Ansu Ånström.
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.
