Saint Petersburg

Saint Petersburg (Russian: Санкт-Петербург, tr. Sankt-Peterburg), formerly known as Petrograd (1914–1924) and later Leningrad (1924–1991), is the second-largest city in Russia. It is situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, with a population of roughly 5.4 million residents.[9] Saint Petersburg is the fourth-most populous city in Europe, the most populous city on the Baltic Sea, as well as the world's northernmost city with over 1 million residents. As Russia's Imperial capital, and a historically strategic port, it is governed as a federal city.

The city was founded by Tsar Peter the Great on 27 May 1703 on the site of a captured Swedish fortress, and was named after apostle Saint Peter. Saint Petersburg is historically and culturally associated with the birth of the Russian Empire and Russia's entry into modern history as a European great power. It served as a capital of the Tsardom of Russia, and the subsequent Russian Empire, from 1713 to 1918 (being replaced by Moscow for a short period of time between 1728 and 1730). After the October Revolution in 1917, the Bolsheviks moved their government to Moscow.
