Saint Petersburg

Saint Petersburg is the second largest city in Russia, politically incorporated as a federal subject (a federal city).
It is located on the Neva River at the head of the Gulf of Finland on the Baltic Sea.
In 1914 the name of the city was changed from Saint Petersburg to Petrograd, in 1924 to Leningrad, and in 1991, back to Saint Petersburg.
In Russian literature, informal documents, and discourse, the word "Saint" is usually omitted, leaving "Petersburg".
In casual conversation Russians may drop the "burg" as well, referring to it as "Piter".
