Bunker-42 is a former Soviet nuclear bunker and command facility located in downtown Moscow. Constructed in 1956 during the Cold War, it was designed as a secure, self-contained underground fortress to protect government personnel and operations in the event of a nuclear attack. Its deep underground construction and robust design were intended to withstand extreme conditions, including a direct nuclear strike.
Today, the facility has been repurposed and operates as a museum and tourist attraction, offering public tours that showcase its Cold War-era infrastructure and history. It serves as a significant historical site representing the era of nuclear deterrence and civil defense preparations in the Soviet Union.
