Finland was a part of Sweden until 1809, and the national parish of the Finnish Church was established in Stockholm in 1533, at the time accommodated in the old abbey of the Blackfriars. A building constructed on the present site 1648-1653, originally intended for ball games, and thus called Lilla bollhuset ('Small Ball House'), but mostly used as a theatre, was taken over by the Finnish parish in 1725 from when the irregularly shaped building stems. In the interior, the organ loft still resembles the gallery of the old Boll House. As the church never had an accompanying graveyard, the Church of Catherine on Södermalmwas of great importance to the Finnish parish until the 19th century.
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.
