Haslum church was built in c. 1190 in Romanesque style. It is possible that it was built by Cistercian monks who also built Halvard Cathedral in Oslo. The original long nave was altered to cross shape in the 1200s. In 1300 there were 12 altars in the church. Haslum church was reconstructed in 1853 and restored to the medieval appearance in 1924.
The wooden statues of the Virgin Mary and the Bishop are copies of medieval originals that have been moved to the Antiquities Collection at the University of Oslo. The Renaissance altarpiece (1631) and pulpit (1590-1642), as well as the baroque baptismal font (1736) are worth of seeing. The paintings on the ceiling were executed by Axel Revold in 1920.
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.
