St. Nicholas' Church stands besides one of Germany's oldest manmade waterways, the Frischen Grube, and was dedicated as the church for sailors and fishermen. The 37m high nave is almost the height of the Marienkirche in Lübeck. The protruding northern and southern vestibules that resemble the arms of a transept are also a particular feature of the church. The lavishly adorned southern gable takes a special place in art of brick construction due to its wealth of glazed figured bricks. From St. Nikolai's medieval interior decoration survives a late-thirteenthcentury granite baptismal font and a maritime altarpiece made in the early nineteenthcentury, but the church's interior is chiefly characterized by completely preserved baroque furnishings.
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.
