History of Cadets' Line name

Kadetskaya liniya (Cadets' Line) was given its name after the 18th century military academy (Rus. Первый Кадетский корпус (Perviy Kadetskiy korpus 1st Cadets' Corps)). The academy was located at the beginning of the street in the land originally granted by Peter the Great to his powerful courtier Alexander Menshikov. The academy was granted the plot including the Menshikov Palace after Menshikov's fall from power.

For the greater part of the 20th century the described side of the street had a different, yet related name until it was changed back in the 21st century. It was called Syezdovskaya liniya (Съездовская линия Congress Line) after the fateful interrevolutionary 1917 Congress of Workers' and Peasants' Councils (Rus. Soviets) held on the premises of the academy, at which, after a Menshevik politician Irakli Tsereteli's statement in his public address that at that moment in Russia there was no political party that could and would take the sole responsibility for the country (i.e., become the ruling party on its own), Vladimir Lenin, the leader of Bolsheviks, said that there was such a party, namely his own one. On October 25 (Old Style), 1917, the Bolshevik faction of the Russian Socialist Democratic Labor Party took power in Russia, and the famous congress and remark were to be commemorated.

Slant Line and Tanners' Line

In the south-western, still industrial, part of the island (beginning to be redeveloped) there is Line that does not follow the rest of the list either in its direction or in its name. It is Kosaya liniya (Rus. Косая линия "Slant Line"). It has one name for both its sides and goes "slantwise", dividing at the crossroads the right angle between Bolshoy Prospekt and 22nd–23rd Line(s).

The only other example of verbal designation of a "line" street in that factory-packed part of the island is Kozhevennaya liniya (Tanners' or Leather Line), whose name is a tribute to a formerly considerable branch of local industry.

Mendeleyev/Mendeleev Line and Stock Exchange Line

At the other end of the island, near its famous east end, full of scientific and museum institutions, there are two other verbally named line streets which run nearly coaxially to each other.

On the one starting from University Embankment (Universitetskaya Embankment) looks the front of the Twelve Collegia Petrine Baroque that now houses Saint Petersburg State University. In 19th and early 20th century the building, belonging to Russia's Head Institute of Education (Rus. Главный педагогический институт) contained the office and living premises of one of its most famous professors - the chemist Dmitry Mendeleyev, and the street was later called after him Mendeleyevskaya liniya (Mendeleyev Line). The Twelve Collegia building now is home to Mendeleyev Memorial Apartment Museum.

At the end of that longish edifice the street flows into a square completely surrounded by places of learning: the main building of the university with its Head Office and Biology and Soil School, another building with its History and Philosophy Schools, yet another one with the celebrated Library of the Russian Academy of Sciences, and the State Optics Institute. These form what is now known as Andrei Sakharov Square, from which the passage along to the opposite embankment continues a little to the left and is known as Birzhevaya liniya (Биржевая линия, Stock Exchange Line) after the Old Saint Petersburg Stock Exchange, whose historic building (recently vacated by the Russian Central Naval Museum) is located just a little to the east.
