Saint Petersburg
federal city and former capital of Russia

Saint Petersburg, formerly known as Petrograd (Петроград), later Leningrad (Ленинград), is the second-largest city in Russia, after Moscow, the nation's capital. Situated on the Neva River at the head of the Gulf of Finland on the Baltic Sea, its area of 1,439 square kilometers (556 sq mi) makes it the smallest administrative division of Russia by area. The city had a population of 5,601,911 residents as of 2021, with more than 6.4 million people living in the metropolitan area. Saint Petersburg is the fourth-most populous city in Europe, the most populous city on the Baltic Sea, and the world's northernmost city of more than 1 million residents. As the former capital of the Russian Empire, and a historically strategic Baltic 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 the apostle Saint Peter. In Russia, 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 1712 to 1918 (being replaced by Moscow for a short period between 1728 and 1730). After the October Revolution in 1917, the Bolsheviks moved their government to Moscow. The city was renamed Leningrad after Lenin's death in 1924.

Why this record matters
“Saint Petersburg” is worth following because a concise public description often conceals a longer documentary argument. Here, Saint, Petersburg and federal provides the most credible route into that argument.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 20, 2026. The linked authority identifier is Q656. VIAF identifies the subject as 561154381054530291788. The Library of Congress control number is n81039599. Authority coordinates are 59.950, 30.317. 2 of 11 selected statements include explicit references; 3 carry qualifiers and 0 use preferred rank. The first chronological checks are 2021, 1703, 1712 and 1918.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
