Question: what other names has st petersburg?
Answer: On 26 January 1924, shortly after the death of Vladimir Lenin, it was renamed to Leningrad (Russian: Ленинград, IPA: [lʲɪnʲɪnˈgrat]), meaning "Lenin's City". On 6 September 1991, the original name, Sankt-Peterburg, was returned by citywide referendum. Today, in English the city is known as "Saint Petersburg".
