Construction of Fredriksten started in 1661 after Norway lost the Bohuslän district and Bohus Fortress to Sweden in 1658. Three subsequent attacks by the Swedes on Halden in 1658-1660 convinced Fredrik 3. the King of Denmark and Norway; a strong, modern fortress was needed. During the war in 1718, Swedish King Karl 12. fell before the walls of Fredriksten fortress.
The fortress offers a fantastic view of the town and the fjord, and far into what once was enemy territory.
