St. Paul's Church (Pauluskirche) was constructed between 1898 and 1901 by Karl Moser (1860–1936) and Robert Curjel and features a Neo-Romanesque architectural style. The apse is fitted with a stone pulpit that is raised behind a stone communion table. The apse also features a gallery, with a central arch behind the pulpit, in which the organ and choir are placed.
It features artwork in Art Nouveau style including relief work on the church exterior above the main entrance by sculptor Carl Burckhardt (1878–1923), mosaics on the inner front wall by Heinrich Altherr (1878–1947) and stained glass windows by Max Laeuger (1864–1952).
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.
