A Cold War-era nuclear bunker located near Środkowa Odra, Poland, part of the Soviet military infrastructure established during the Cold War. This bunker was part of a network of clandestine sites that once housed hundreds of nuclear warheads, kept secret from the Polish population. The bunker represents the extensive Soviet military presence in southwestern Poland during the Cold War period, when the region was dotted with airbases, ghost towns, and fortified installations.
These facilities were part of the Warsaw Pact's strategic defense network and remained classified until after the fall of the Soviet Union.
