This is an extensive list of Russian/Soviet place and personage names, all of which were hastily imposed on locations in Prague after the 1968 crackdown to “Soviet-ize” the city.
Briefly, Baikal is a giant freshwater lake (the second most voluminous in the world, after the Caspian Sea, and also one of the deepest and clearest), located in Siberia. The photograph above is a view of Lake Baikal from space, taken by the OrbView-2 satellite in 2003.
Moscow is of course the capital city of Russia, Stalingrad one of the larger cities (now known as Volgograd and sometimes in the past Tsaritsyn), and Leningrad a sometime capital which reverted to its older name of St. Petersburg after the fall of the Soviet Union in 1991.
Rostov, Novosibirsk, Kiev, and Odessa are other noted (former) Soviet cities. Respectively, they are one of Russia's oldest cities, on Lake Nero northeast of Moscow; the third largest, in the center of the continent, at the western edge of Siberia; the capital of the Ukraine; and a port on the Black Sea.
The rest of the names are noted Russians: Pyotr Ilyich Tchaikovsky the composer (“The Nutcracker”), Leo Tolstoy the novelist (War and Peace), Nicolai Rimsky-Korsakov the composer (“Scheherazade”), Alexander Suvorov a great 18th-century Russian general, Maxim Gorky the author (a founder of socialist realism; see Bookmarks, pages 63 and 91), and Alexander Pushkin the poet (“Boris Godunov” and “Eugene Onegin”).
