In 1701 Peter the Great established a special school, the School of Mathematics and Navigation (Russian: Школа математических и навигацких наук), situated in the Sukharev Tower in Moscow. As the territory to the west around the Gulf of Finland was acquired by Russia for a "warm-water" port giving access for its merchantmen and the buildup of a naval force, the city of St. Petersburg was built and developed an extensive port. The School of Mathematics and Navigation was moved to St. Petersburg and in 1752 it was renamed the Naval Cadet Corps.
