The Moscow Metro is the world's most heavily used metro system. Kievskaya station is one of the oldest stations on the network and lies on the Kol'tsevaya line (the central ring line) which was completed in 1937. Several of the central stations are remarkable for their ornate architecture, with marble columns, granite floors and chandeliers. Kievskaya station is particularly noted for its wall mosaics which depict socialist realist scenes from the history of the Ukraine.
