Oseberghaugen is a Viking era burial mound. The Oseberg ship was found in the Oseberg burial mound in 1904. This Viking longship is now in the Viking Ship Museum in Oslo. Archaeological excavations in 1904 uncovered history's largest and richest example of craftmanship from the Viking Age. In addition to the Oseberg ship, Oseberghaugen contained the Oseberg carriage, five beautifully carved bed-posts shaped like animal heads, four sledges, beds, chests, weaving-frames, household utensils and much more. Scientific examinations in 1992 now date the burial to 834 AD, and indicate a probability that it was Queen Alvhild, the first wife ofKing Gudrød, who was buried here.
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.
