As we previously mentioned, there are a lot of hidden, unknown places in Russia, but this time it is situated in Moscow – the nation’s capital. Metro-2 is a nickname given to the metro line, which is rumored to have been constructed in parallel to the actual metro that is open to the public. Also codenamed as D6 by the KGB(USSR’s equivalent of CIA), it was apparently built under Stalin. The purpose was to link the strategic points in Moscow, such as Kremlin and the KGB headquarters, should a nuclear war/ total disaster break out. No one is exactly sure whether it is still in use, or how far exactly it reaches, but explorers in Moscow seemed to have discovered an entrance.
