Saint Petersburg (short: SPb, Russian: Санкт-Петербург) is a city of Russia located on the Neva River at the head of the Gulf of Finland on the Baltic Sea. It is informally known as Piter (Пи́тер). SPb is the northernmost city of the world with over one million people. SPb is often described as the most Westeuropean city of Russia. From 1924 to 1991, in honor of Lenin, the founder of the Soviet Union, the city was called Leningrad (Ленинград).
The church is the "Peter and Paul" cathedral. The main religions in Russia are the Christianity (above all the Russian-orthodox faith) as well as the Islam. In addition, numerous others are represented like Judaism, Buddhism and traditional religious directions of some ethnic groups. Nevertheless, at least one third of the Russian population calls itself atheists!
