Greåker Fort

Greåker Fort is a military fortification sitting on a steep hill that overlooks the Glomma river and contains underground chambers, ammunition storage, and former gun positions. The structure occupies the elevated terrain and displays chambers below ground as well as old gun emplacements at ground level.

The fortification was built between 1902 and 1903 as a response to tensions between Norway and Sweden at that time. In spring 1940, the garrison defended itself against German forces.

The fort represents how Norway prepared militarily during a time of regional tension and independence. It shows the country's determination to protect itself.

The site sits in a residential area and is reachable on foot, where visitors can see the sealed entrances and preserved grounds around it. Sturdy shoes are helpful since the terrain is uneven and the hilltop view requires some effort to reach.

The interior is not open to visitors, but the structure itself still shows the original gun turrets and their orientation toward strategic river passages. This makes the fort a valuable example of military architecture from that era.
