* St. Petersburg is one of the most beautiful cities in the world. They call it Northern Venice and Northern Palmyra, the Cradle of the Revolution and the Cultural Capital of Russia, but perhaps the most correct name is the Open–air Museum. Indeed, the entire historical center of St. Petersburg is one continuous museum complex of palaces, mansions, temples, canals, embankments, avenues, art and memorial museums. It is no coincidence that the entire city center is protected by UNESCO as a unique historical monument and architects. I invite you to visit this museum.
