Riding the Moscow metro

People walk through Prospekt Mira metro station in Moscow August 14, 2013. To step onto the Moscow metro is to step back in time and immerse yourself in a museum rich in architecture and history. Opened in 1935, it is an extravagant gallery of Communist design, featuring Soviet artworks, statues, chandeliers, stained glass and ceiling mosaics. Built under Stalin, the metro now transports 7 to 9 million people a day and costs 30 Rubles, around $1, for a single ride. [Photo/Agencies]
