Visit to the St. Petersburg metro. Considered a symbol of strength by the Soviet government, it represents the industrial and technologic progress of the political system. It is also a major engineering achievement due to the difficulty presented by the marshy and unstable ground under the city, and is the deepest metro network in the world, being also designed as a nuclear bomb shelter. The first plans were drawn up in 1899, but the Communist revolution and the capital’s move from St. Petersburg to Moscow halted progress, and, due to resume in 1930, World War II stopped its construction yet again. Since its opening in 1955, almost three million passengers have been transported every day. The beauty of some of its stations rivals the Moscow metro system, with different styled decorations, including the majestic Stalinist style.
