Bunker-42 is a former Soviet underground fortification located in downtown Moscow, Russia. Constructed during the Cold War era, this facility was designed as part of the USSR's defensive strategy following the United States' development of nuclear weapons. The bunker sits 65 meters beneath the surface and was originally built to protect Soviet leadership in the event of a nuclear attack.
Today, Bunker-42 operates as a Cold War museum, offering visitors a glimpse into this pivotal period of military history through guided tours that showcase the facility's strategic importance and preserved interior spaces.
