St. Paul's Chapter Church was built by Bishop Burchard (who also built the first Worms Cathedral) in 1002. It was originally a three-naved buttress basilica.
A Dominican monastery was added in 1226. Also in the 13th century, the stone dome-shaped tower roofs were added in the Byzantine style of Jerusalem's churches. These make the church a visible monument to the Crusades.
The Pauluskirche was desconsecrated and the monastery destroyed in 1797 in the interests of secularization. In the decades that followed, the church was used as a warehouse, a barn and finally as a municipal museum (1880).
In 1929, Dominican religious life began again here and is still an active community. The resident monks conduct services, prayers and confession, and some also work as hospital or prison chaplains. The Pauluskirche was badly damaged by bombing on February 21, 1945, but through the support of local citizens it was rebuilt and back in service in 1947.
The present nave of the Pauluskirche was rebuilt in the Baroque era, but the remainder of the building is 11th-century Romanesque.
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.
