St. Petersburg at night. As the sun goes down St. Petersburg offers absolutely different perspectives to the visitor, depending on the season. In winter the splendidly illuminated facades enhance the beauty of the main buildings, monuments, squares, and palaces, showing a new aspect of the city, especially on the scenic embankments along the frozen Neva. In summer, especially during the period known as the White Nights, a captivating semi-daylight surprises the visitor. Raising the city bridges every night allows ships to cross the city center, creating a one-of-a-kind spectacle. The image of the raised bridges is a symbol of the city and an unforgettable memory for the traveller.
