(The Metro!) Believe it or not, it’s a tourist attraction in and of itself!  Gorgeous chandeliers, bronze statues and tile mosaics adorn the walls and ceilings of the world’s most beautiful public transportation system.  Start at Komsomolskaya and make your way around to Prospekt Mira, Novoslobodskaya, Krasnopresnenskaya, Kievskaya, Ploshchad Revolyutsii, Teatralnaya & Mayakovskaya in that order.
