Kalmar Church was built of granite in the late 12th century. Around 1300 it was enlarged and modified to the aisleless Gothic church. In 1485 famous Albertus Pictor decorated walls and vaults with murals. Frescoes were restored in 1958 and still visible. Th current tower was added in 1830. There is font with a cuppa, made of red sandstone, from the late 1100s and medieval wooden sculptures (like a triptych from the mid-1400s) in the church.

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.
