Kongsten Fort is one of Fredrikstad’s many unique historical heritage sites. Built in 1685 in conjunction with the fortified town, the fort was part of the city’s extensive defensive system. The complex is known for its thick stone walls, casemates, and important historical role in the defense of the city.
The fort was nicknamed Svenske Skremme (“Swede-Scarer”) because it was built to protect Fredrikstad from attacks from the east, particularly from Sweden.
Kongsten Fort is situated on a hill directly east of the Old Town in Fredrikstad. It was built in 1685 to protect the city’s main fortress against land-based attacks and served as a freestanding outlying fort that strengthened the defenses of the fortified town.
The fort is one of Norway’s best-preserved bastion fortresses, with its historic walls, buildings, and underground casemates still visible. Some areas are open to visitors.
As the town fortifications neared completion, Kongsten Fort featured high defensive walls and followed the Italian system of fortification. The design incorporated hornworks, redans, curtain walls, and tenaille structures.
During the construction period, the fort was known as Königsten. Following an inspection by King Christian V in 1685, it was referred to as Christianstein. After a couple of years, however, the name reverted to Königsten.
The fort was built on rocky outcrops. To the north was the somewhat gently sloping and rounded Galgeberg. A little higher outcrop lies farther south and has steep slopes, particularly on the eastern side facing Sweden.
Before returning home from Fredrikstad, we wanted to visit the Kongsten fort, which is very close to Gamlebyen Old Town of Fredrikstad. It was an almost 7-8 minute drive. A very good parking place for visitors. There are no fees for going around the fort. After parking, we started approaching the fort.
From a long distance, the fort looks very beautiful with lush green trees and bushes.
As we climbed the stairs toward the fort, I took this photo of the surrounding landscape. The area is green and open, with patches of grass and trees, giving it the appearance of a recreational area or park-like embankment.
Today, the area is a popular outdoor recreation spot, with historic buildings, pleasant walking paths, and excellent views of the city.
While climbing the stairs, on the left side, before the entrance, we can see a solid granite wall showing a section of the historic fortifications, featuring a small, framed vent or loophole in the wall.
The entrance was built into a defensive wall structure called a portkurtine (gate curtain wall), which combines heavy defensive masonry with symbolic royal craftsmanship
From the entrance, we can feel the peaceful, pleasant atmosphere.
A stone building with a vaulted gateway serves as one of the entrances to the fortress area.
A plaque at the fort explains that the site was controlled by German forces during the Second World War (1940–1945). During the occupation, it was used for purposes including a weapons depot and a prison.
At the time of liberation in 1945, the Home Front secured a peaceful transition of control.
The original plaque, installed in 1995, was stolen several years ago. A replica was installed in 2025.
After getting inside the entrance, we can see there were also some smaller wooden stairs leading toward the golf course located beside the fort.
After entering the fort, we could see a large building on the right. This is one of the main historic structures within the fort complex. This two-story building was originally established in the 17th century as part of the outlying defenses of Fredrikstad Fortress.
The building is the Provision Magazine (Proviantmagasinet), which was used to store provisions for the fortress. The building has been renovated and is now available for private gatherings and cultural activities. It has approximately 60 guests' seating capacity.
The surrounding area has occasionally been cordoned off because loose roof tiles have fallen from the roof structure. It looks like there was some work ongoing.
The Commandant’s Residence originally served as the home of the fort’s commandant.
The residence features a cozy room with a fireplace and seating for approximately 30 guests. Today, it is primarily used to supplement the Provision Magazine and can be used (renting) for private gatherings and other events.
On the day of our visit, there was a private gathering taking place, and several women were preparing decorations. Because of the event, access to the building was somewhat restricted.
From the rear, I noticed the building’s distinctive thick rubble-stone walls and decorative brickwork around the windows. The door also appeared to be a more recently renovated part of the building.
This is the outer defensive perimeter wall of the fort. It is constructed from large, irregular granite blocks and was designed according to traditional Italian fortification principles.
The thick stone walls were intended to absorb and withstand cannon fire. A small iron-grated opening in the wall may have served as a window or ventilation opening leading into one of the fort’s underground casemates.
Visitors can walk through several parts of the fort, although some areas are very steep and do not have railings. It is therefore a good idea to walk carefully, particularly near the edges and on the steeper sections.
From the higher parts of Kongsten Fort, we can see Fredrikstad’s Old Town as well as the bridge crossing the Glomma River.
The combination of historic fortifications, open green spaces, and views across the city makes Kongsten Fort an interesting place to explore and an important part of Fredrikstad’s cultural heritage.
Kongsten Fort is owned and managed by Fredrikstad Museum. The Provision Magazine, the Commandant’s Residence, the casemates, and parts of the outdoor area are available for rent for social gatherings, cultural activities, and other events.
Thank you very much!
