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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
