Archaeologists have uncovered the Chieftain House at Borg in Lofoten (""), a large Viking Era building believed to have been already established around the year 500. Archaeological studies commenced here in 1983 and in 1986–89, a joint Scandinavian research project was conducted at Borg. Excavations brought to light remains of the largest building ever to be found from the Viking Era in Norway, 83 meters long and 9 meters high. The chieftain's seat at Borg is estimated to have been abandoned around AD 950. Today the site is the location of the Lofotr Viking Museum.
