Bulverket

The Bulverket, located in Lake Tingstäde on Gotland, Sweden, is a significant archaeological site dating to the 12th century CE. It represents a large wooden fortification built as a shelter during the turbulent end of the Viking Age. The structure featured a platform with houses surrounded by a double palisade, covering a diameter of about 250 meters. Despite its purpose remaining uncertain, it is believed to have served as a refuge or potentially a trading hub during a time of social upheaval and external threats. Archaeological finds include well-preserved wooden remains and boats, with one vessel serving as a model for reconstructed Viking ships. The site reflects influences from Slavic or Baltic styles, highlighting its cultural and historical significance.
