The Lofotr Viking Museum is a historical museum based on a reconstruction and archaeological excavation of a Viking chieftain's village on the island of Vestvågøya. In 1983, archaeologists uncovered the Chieftain House at Borg, a large Viking Era building believed to have been already established around the year 500 AD. A joint Scandinavian research project was conducted at Borg from 1986 until 1989. Excavations revealed the largest building ever to be found from the Viking period in Norway. The foundation of the Chieftain House at Borg measured 83 metres long and 9 metres high. The seat at Borg is estimated to have been abandoned around AD 950.
After the excavation ended, the remains of what had once been the long-house remained visible. The long-house has been reconstructed slightly to the north of the excavation site. In 1995, the Lofotr Viking Museum was opened. The museum includes a full reconstruction of the 83-metre long chieftain's house, a blacksmith's forge, two ships (replicas of the Gokstad ship, one in full scale size) and their boathouses, and various reenactments intended to immerse the visitor in life at the time of the Vikings. The main building was designed by Norwegian architect, Gisle Jakhelln.
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.
