St. Petersburg is known for grand palaces and lavish mansions that all tourists flock to in their hundreds if not thousands. Of course, coming to St. Petersburg and not visiting Peterhof or the Winter Palace would amount to a crime against culture and history. But once you’ve ticked off these touristic musts, why not leave the masses and dip out to some of the lesser known mansions, some of which are abandoned and borderline derelict but still so full of charm and Instagram potential. Although largely unknown and passed by, it would be difficult to imagine the Northern Capital without these architectural masterpieces.
