Let's go off the beaten track and take a look at the courtyards, hidden from the eyes of tourists. We will stop over at one of the magnificent entrance hallways of old houses, which are decorated to match the Imperial Petersburg. And a final culminate in uplift on the roof of the famous Singer House. It is the dream of every resident and guest of St. Petersburg! This exquisite dome is located in the very heart of the city, offering a breathtaking panorama of the best views.
