This tradition began here after the end of World War II, when schools united to celebrate the ending of a school year in connection with symbolism of the popular children's book "Scarlet Sails" by Alexander Grin. At that time a boat with scarlet sails was sailing along the English Embankment and the Admiralty Embankment towards the Winter Palace. Although it was designed to update the rusty revolutionary propaganda, the "Scarlet Sails" tradition has become a popular public event, annually celebrating the ending of the school year in June. The "Scarlet sails" appearance is now the most popular part of the White Nights celebration.
