The Neva River splits into a delta in St. Petersburg, which was the Russian capital at the time of the revolution. Thanks to this network of waterways, St. Petersburg is often called the Venice of the North..olga River. The Volga River is the most important river in Russia.

Approximately half of the country's 20 largest cities are in the Volga basin, including the capital of Moscow.
