Dendrochronological dating of wood samples indicate that Nore stave church was built after 1167. The church was built with galleries, a chancel and cross naves - an architectural style that was unique in Europe during the Middle Ages. This style is called the Nummedals-type. The church also has a central mast, that was originally the support for a tower, mostly likely containing church bells. The walls and ceiling of the interior are decorated with murals, among them scenes from the Bible presented as riddles. The chancel was replaced in 1683 and the spokes of the nave in the first half of 18th century.
In 1888, art historian, professor of art history and author, Lorentz Dietrichson (1834 - 1917), became the owner of the church. Professor Dietrichson, who had played a major role in founding the Society for the Preservation of Ancient Norwegian Monuments (Fortidsminneforeningen), donated the property to the society in 1890.
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.
