Bunker-703

This atmospheric location on the surface is masked by an inconspicuous gray building. However, the true nature of this location is hidden more than 100 feet underground, similar in-depth to the Moscow underground/subway (Metro). This former bunker was constructed during the Cold War and wasn’t declassified until 2018.

The purpose of the bunker was to act as a protected storage facility for some of Russia’s most important foreign policy documents. It’s believed that around 120 tons of documentation, from treaties to top-secret materials were housed inside this bunker.

Although no longer used by the government, the bunker’s Cold War atmosphere still remains. To enter, visitors must venture down a set of stairs that take them underground. A local guide is available to conduct tours of the bunker and provide information about the facility’s history.
