Tønsberg Fortress

The origins of Tønsberg date back to 871, making it one of Norway's oldest cities. According to Snorri Sturluson, it was founded before the Battle of Hafrsfjord under King Harald I. In the 13th century, King Haakon Haakonsson had Tunsberghus Castle built on this strategically important site. The fortress was the scene of significant events, including a five-month siege by King Sverre Sigurdsson in 1201. Later, it served as a residence for King Magnus Lagabøter and his wife Ingeborg of Denmark. King Haakon V Magnusson died here in 1319, and in 1335, King Magnus Eriksson married Blanche of Namur at the fortress. In 1503, during the collapse of the Kalmar Union, the complex was destroyed by Swedish soldiers and local farmers.

Tønsberg Fortress is located in the city of Tønsberg, in the Vestfold district, within the Østlandet region of Norway. It is situated at an elevation of approximately 53 meters above sea level.

Today, only ruins remain of the once imposing Tønsberg Fortress. A prominent tower, built in 1888 as a monument to the historic fortress, characterizes the site. The fortress is open to visitors, offering insights into its rich past.
