"Gazprom" is the biggest Russian corporation, worth over $200 billion, translated as "Gas Production".
It serves gas and oil to the whole Europe, people in Russia often make jokes that Gazprom keeps Russia just like a servant for itself, and if there would be some need for "Gazprom" to join Europe to Russian Federation it would be done next day without any problems because all the Europe depends on Russian gas. Also some analytics say that Putin after his presidency ends would head Gazprom.

People of St. Petersburg demand to stop this projects in coming to life because they want to preserve "cultural and architectural unity of the city". But if Gazprom wants something nobody can say something to it.
Look what they going to build in St. Petersburg:
