During the Cold War, Sweden had a large number of military warehouses deployed deep in the forests. In the event of war, the defense could easily continue even if the cities were severely bombed. However, a warehouse of this size is unusual.
We are a few kilometers from the nearest town center. Forest and mountain dominate the area. The availability of large hard mountains gave the opportunity to build really large mountain spaces. In addition, the large forests would keep the most curious in distance.
Thus a perfect place for secrecy and trucks that traceless disappear into the mountain.
Construction of the secret facility
The tunnel divides in two directions. If you get it uphill, you will come to the heart of the plant. There are storage rooms of size as a living room to a soccer field. I assume that depending on the content, the rooms were differently suitable depending on the weapon and ammunition type.
Now the walls drip moisture. The mold hangs in clusters and without ventilation, the condition will only get worse. No natural ventilation is hardly available either. The facility is really locked in.
Finally, I apologize for the quality of the pictures. They are actually taken with a system camera, but an extreme darkness in combination with extreme humidity created a fog that made impossible points for the camera to focus on.
