Visit this decommissioned military bunker for a close brush with real history. It was here in October 1962 that Stalin's successor, Nikita Khrushchev, hid away during the Cuban missile crisis. The Russian government sold the bunker in 2006 to a private company that has turned it into a Cold War museum and entertainment complex, with some parts still under construction. The tour takes you 18 floors underground, either via an elevator or stairs. The hands-on tour gives you the opportunity to try on old Soviet military uniforms and even play with the AK-47s that are on display (they aren't loaded, of course). Tickets are expensive, but well worth it. Be sure to book before going, however, because as one might expect from a place once owned by the KGB, individual unannounced visits are not allowed.
