Stock Photo - 02 June 2021, Russia, St. Petersburg: The ""Big House"", as it is called in St. Petersburg, is the headquarters of the local domestic intelligence service FSB, which used to house the Soviet secret service KGB, where Vladimir Putin made his career as an officer. Formerly the metropolis of the tsars, St. Petersburg is the hometown of Kremlin leader Putin. When the megacity, popular with tourists, was still called Leningrad, he grew up here in poor conditions, as can be learned on the city tour ""Putin in Petersburg"".
