Siemens Velaro RUS Sapsan, Moscow, St. Petersburg

Having passed the role of capital to Petersburg, Moscow never relinquished the title of 'capital', being called "pervoprestolnaya" ("first-throned") for 200 years. A mirroring name for Petersburg in this connotation, the "Northern Capital", is reintroduced today in the sense that several federal institutions were moved from Moscow to Petersburg recently. Solemn descriptive names like "the city of three revolutions" and "the cradle of the October revolution" used in Soviet era reminded the pivot events of national history which occurred there. For their part, poetic names of the city, like the "Venice of the North" and the "Northern Palmyra" emphasize town-planning and architectural features contrasting these parallels to the northern location of this megalopolis. Petropolis is a translation of a city name to Greek, and is also a kind of descriptive name: Πέτρ~ is a Greek root for "stone", so the "city from stone" emphasizes the material which had been forcibly made obligatory for construction from the very first years of the city.
After 1991 a wave of re-namings started within the city. It affected not only toponyms of the Soviet era, but in some cases their pre-revolutionary ones (in 1993 Gogol Street which bore the name of Nikolai Gogol since 1902, was renamed to Malaya Morskaya).
