A subway, a nuclear bunker and a museum of soviet industrialization era

The Moscow Subway is not merely a series of trains and tunnels. Its stations are living museums, functional works of art that usher the busy Moscovites about their daily tasks. The system spans the entire city and has the capacity to host the entire population of Moscow (11 million) in the event of an attack. The Moscow Subway is made of marble and granite, each station displaying a different palace-like design. Visitors to Moscow are awed by the sophistication of something as simple as a transportation network.
