* This is a unique tour, during which you will literally and figuratively immerse yourself in the theme of the Subway. Let's talk about how St. Petersburg missed its chance to become a pioneer of underground highways and what daring projects for their construction were considered at different times, how the metro was built, and what difficulties the metro builders had to face. We will look at the differences between the St. Petersburg metro and the metropolitan metro, the types of stations and the specifics of their construction. The route is designed in such a way as to cover the iconic stations of the first and most elegant branch, including the pearl of our Metro station Narvskaya. According to many media outlets, Elon Musk noted it as the most beautiful station in the world. However, we will not limit our impressions to underground palaces and will get acquainted with later and technically advanced stations, visit the deepest underground lobby, find out what a horizontal elevator is and why it is needed in the subway. We will find the only preserved image of Stalin in our city, see the first underground monument in the world, and even examine 200 million-year-old fossils. Let's also recall the difficult wartime and how the metro builders saved Leningrad during the Siege.
