The Church of St. Andreas was constructed between 1622 and 1629 in the South German baroque style. It was originally a Jesuit church and also served as the court church for the Counts palatine of Neuburg. After the dissolution of the Jesuit order in August 1773 it served as a parish church until 2005 when it became the monastery church of the Dominican Order. The building itself is now owned by the city of Düsseldorf.
The church is furnished with stucco by Johannes Kuhn from Strassburg and life-size sculptures of the apostles and of saints of the Society of Jesus.
In the late 17th and early 18th centuries, the church was an important center of musical culture in Düsseldorf. The composer Johann Hugo von Wilderer served as its organist. The mausoleum, designed by Venetian architect Simone del Sarto, contains the tombs of several Electors Palatine, including that of Johann Wilhelm. The high altar of the church was destroyed during World War II. The new altar, designed by Ewald Mataré was built in 1960. Paintings by Ernst Deger can be found in the church's two side altars which are dedicated to the Virgin Mary.
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.
