Archaeological findings Several Viking ships in burial mounds have been found and placed in museums, including the Oseberg and Gokstad ships. In October 2018, Norwegian archaeologists headed by the archaeologist Lars Gustavsen announced the discovery of a buried 20 m long Gjellestad Viking ship in Halden Municipality. An ancient well-preserved Viking cemetery for more than 1000 years was discovered using ground-penetrating radar. Archaeologists also revealed at least seven other previously unknown burial mounds and the remnants of five longhouses with the help of the radar survey.
