Komsomolskaya Metro Station, Moscow, Russia.

The construction of  the  Metro station at  Komsomolskaya  began on May 1933, and opened the same month two years later in 1935. The station was built with an unusual upper gallery above the platform on the Sokolnicheskaya Line (line № 1) to help the rush of people. One of the architect of the project wrote that the station has been thought as one of the busiest one in Moscow and the gate of the city for many visitors, so it needed to be designed as to give the best first impression of the capital as possible.
