This small church on Rüütli street has been the spiritual home for generations of Estonian Swedes, an ethnic group that's been present in Tallinn since the Middle Ages. The location had originally been an almshouse for the city's poor, but in 1733 the tsarist government gave it to the Swedish congregation, which been left without its own church since the Great Northern War.
During Soviet times the building was converted into a sports hall and fell into disrepair, but was renovated and reconsecrated in 2002. It now has a congregation of around 200, and continues to hold services in Swedish. In addition to its Baroque altar by Joachim Armbrust and a Baroque pulpit, the church has a unique baptistery created by famed sculptor Christian Ackermann in 1680.
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.
