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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
