A subterranean art gallery filled with chandeliers, marble, mosaics, and statues depicting Soviet Union farmworkers, Saint Petersburg’s metro is the world’s deepest and busiest underground. Opened in 1955, stations, such as the 279 feet deep Admiralteyskaya, doubled as bomb shelters during the Cold War, hence the big blast doors and air filters.
You can traverse five subway lines, 67 stations, and 3 000 trains for just 45 Rubles.
Near the Narvskaya station, the Narva Triumphal Gate (built 1814) celebrates Russia’s victory over Napoleon. Newsky Prospect on the Moskovsko-Petrogradskaya line is to St Petersburg what the Champs Elysees is to Paris – the pulsing main artery lined with 18th-century homes and neoclassical monuments.
