The Moscow Metro, known for its architectural grandeur and efficiency, is one of the most iconic subway systems in the world. Opened in 1935, it is not only a transportation system but also a vast underground art museum, often termed as 'the people’s palaces.' Lavishly decorated with marble, mosaics, stained-glass windows, and sculptures, the stations reflect various architectural styles and themes in Soviet history. Each station has its unique aesthetic, telling the story of Russia’s past glory and aspirations. With over 200 stations and more than a dozen lines, the Moscow Metro covers nearly all the central districts and many outlying residential areas. The system is also one of the world's busiest, with millions of passengers daily, owing to its reliability, speed, and low cost. It serves as a vital artery in the bustling metropolitan life of Moscow, connecting people across the vast city with ease and convenience. The Moscow Metro also plays a crucial role during the harsh winter months, providing a warm transit option beneath the city.
