Bunker 105b is a military bunker located in Norway, a country that built extensive fortifications during the Cold War due to its proximity to the USSR. Norway's Cold War military strategy included the construction of numerous bunkers and secret bases as part of its national defense infrastructure. These structures were designed to protect military personnel and equipment in the event of a conflict with the Soviet Union.
The bunker's exact purpose and specifications are not detailed in available sources, but it represents Norway's broader network of Cold War-era military installations.
