The project helps to get acquainted for free with the lesser-known pages of the city's history and its architectural monuments. To participate, you only need to register in advance for the chosen tour. The free educational project opens access to tours of historical buildings and landmark sites, many of which are usually not open for free visits. To attend the event, you need to register on the project’s website, choose an interesting tour, and wait for the registration to start. The number of places is limited, so registration usually ends very quickly. Schedule of upcoming tours: July 15 - "City Giants". A children’s walk that will introduce impressive architectural structures of St. Petersburg and its ancient trees. Participants will enjoy games, interesting facts, and the opportunity to view the city from an unusual angle; July 17 - "Secrets of the Old Courtyard".
