Poland : Bunker

The bunkers are truly massive. To bad you cannot really go inside, well, you can if you have a strong light and don't care about getting dirty. I am sure all weapons and other artifacts were removed long time ago. Please note that there are no turrets and other land defense positions. These bunkers were not for land defense but for air attack defense. This is why Germans blown them up, they could not be used to defend against incoming Russian land forces.
