The Komsomolskaya station of the Moscow Metro is the most famous of all those on the Koltsevaya Line and of the whole system, and an icon of Moscow itself, partly due to it being located on Moscow's busiest transport hub, Komsomolskaya Square, which serves three railway terminals: Leningradsky, Yaroslavsky and Kazansky. The station's connotation is of a gateway to Moscow and to the rest of Russia, and its theme is of the patriotic history and inspiring future of the nation. It was opened on January 30, 1952, as part of the second stage of the Ring line.
