This top secret bunker is located 18 floors beneath Moscow in the Taganskaya area. So close to the metro, there are not only adjoining tunnels but carriages rattling past fill the concrete passageways with a whole lot of groaning noisy sound. Decommissioned and sold off at auction, this ex-military communications post is now a museum dedicated to the Cold War. Complete with KGB rooms (now rehearsal space for heavy metal bands), raid sirens, and kilometres of tunnels, this is the real experience. Guides play the role of KGB officers and the exhibits are all very hands-on. Not recommended for claustrophobes, but definitely for the curious and historically inquisitive. The bunker is also available to hire for functions be there conferences or team-building role play games with lasers and paintballing and so on.
