1947: Object 02 takes shape
The story begins in the atomic age. In autumn 1947, the technical project for a bunker on Tagansky Hill was prepared under the codename Object 02, also linked with ChZ-293. The location mattered: close enough to the Kremlin for emergency command logic, but hidden inside dense central Moscow fabric.
1950-1954: building a secret underground city
Construction began in 1950 with metro-building expertise and a difficult brief: create a huge underground structure without disrupting the city above or exposing the project. The main structures were complete by 1952, life-support systems followed by summer 1953, and the first communications specialists began work in April 1954.
1955-1986: command beneath the city
In 1955-1956, equipment and communications links were installed for strategic bomber units across the Soviet system. For roughly three decades, until 1986, the bunker was tied to command of aircraft carrying nuclear weapons. That history gives the present-day alarms, consoles, and sealed doors their edge.
What you notice underground today
The strongest moment is the shift from ordinary Taganka street life to controlled subterranean space. You pass from a small mansion into tunnels, technical rooms, Soviet-era staging, and Cold War effects that turn abstract nuclear history into something physical. It is theatrical, but the concrete around you is real.
