Kazan Cathedral or Kazanskiy Kafedralniy Sobor, also known as the Cathedral of Our Lady of Kazan, is a cathedral of the Russian Orthodox Church on the Nevsky Prospekt in Saint Petersburg. It is dedicated to Our Lady of Kazan, one of the most venerated icons in Russia.

Nevsky Prospect is a main street located in the federal city of St. Petersburg in Russia. Its name comes from the Alexander Nevsky Lavra, the monastery which stands at the eastern end of the street, and which commemorates the Russian hero Prince Saint Alexander Nevsky (1221–1263). Following his founding of Saint Petersburg in 1703, Tsar Peter I planned the course of the street as the beginning of the road to Novgorod and Moscow. The avenue runs from the Admiralty in the west to the Moscow Railway Station and, after veering slightly southwards at Vosstaniya Square, to the Alexander Nevsky Lavra.
