The Old Town in Fredrikstad with all its beauty hides a well-preserved fortress, placed approximately 500 metres east of the town. This is Kongsten Fort, aka "Swedish-scare". The fortress thrones majestically on a bluff that was given the name Gallows Hill because it was used as the place of execution where the lawless citizens of the town had to end their lives in the gallows.
Today, Kongsten Fort is part of Fredrikstad Museum and owned by the council (since 1942). In the summer you can take part in one of the many guided tours that are arranged. As already mentioned the Supplies Magazine is being let to the public. In the summer there’s a cafeteria in the Colonel’s house.
