The Saint Petersburg metro is remarkably efficient and architecturally beautiful. That's why it's worth a visit even if you don't really need to take it.
Opened in 1955, the metro of St. Petersburg is considered the 12th busiest metro system in the world. It has five lines, 67 stations, 3,500 trains and over 2.5 million passengers each day, and is served by a staff of 12,000 people.
Almost each metro station is a magnificent work of art designed by some of the country’s best architects. So, when you get off the train, don't be surprised to see beautiful statues, mosaics and golden carvings. Each metro station has its own decoration and meaningful story to tell. Some are dedicated to the Russian revolution and the Soviet era, others to great Russian famous writers as Pushkin and Dostoyevsky, while many are dedicated to the victory of Russia in WWII.
