VDNKh (ВДНХ) is a station on the Kaluzhsko-Rizhskaya Line of the Moscow Metro, named for the nearby All-Russia Exhibition Centre. When it opened, on May 1, 1958, it was the northernmost station on the newly completed Rizhskaja Line. The station features pylons faced with white marble and decorated with circular ventilation grilles. VDNKh was designed by Nadezhda Bykova, I.Gokhar-Kharmandaryan, Ivan Taranov, and Yu. Cherepanov. At a depth of 53.5 metres, it is one of the deepest Metro stations. It is also one of the busiest, serving approximately 119,000 passengers per day according to a 1999 study.
Originally, this station was planned to be richly decorated in the manner of the other stations built in the 1950s, with mosaics by V.A. Favorskoi along the insides of the arches between the pylons. However, in the wake of Nikita Khrushchev's attack on decorative "extras," the mosaics were crudely coated with incongruous thick green paint.
The original circular vestibule is on the west side of Prospekt Mira, in front of the Space Obelisk. A second entrance was added at the southern end of the station in 1997.
