Saint Petersburg is Russia's second largest city, with a population of 4.7 million perched at the eastern tip of of the Baltic Sea and the Neva River. The city was formerly known as Petrograd, and later Leningrad.
Since the collapse of the Soviet Union, the city has been rapidly making up for lost time and is by far the most cosmopolitan of Russia's cities. Now formally known by its original name again, most Russians call it what they always have, the friendly diminutive Piter.
