ponds on the boulevard and towards the Myasnitskiye Vorota square. The pavilion links up to the subterranean vestibule and ticket hall. During the reconstruction in 1971, a subway was built directly linking the underground space with the new network of entrances for the Turgenevskaya station, which makes it possible to walk from one station vestibule to the other without descending into the platform halls. The original 3 N-type escalators were replaced in 1995 by ET-3M models (30 metres high {98 ft}), during which the pavilion and vestibule underwent renovation. The station's transfer to Turgenevskaya of the Kaluzhsko-Rizhskaya Line is done via a tunnel that begins underneath Chisye Prudy's platform. Access to which is gained by two sets of two 9.4 metre (30 ft) high LT-5 escalators (northern - ascent, southern - descent), opened 5 January 1972. Transfer to the Sretensky Bulvar station of the Lyublinsko-Dmitrovskaya Line, opened on 13 January 2008, is accomplished by 3 E-25T escalators (23.8 metre high {78 ft}) which begin at the northern end of the central hall and descend into the newer station. Station surroundings The name "Chistye Prudy" also refers to the neighborhood surrounding the Metro station. This area is sometimes called Chistye Prudy or Pokrovka (referring to the street by the same name). In the 16th century, Pokrovskye Vorota (Pokrov Gates) stood at the current intersection of Pokrovka Street and Chistoprudny Boulevard. The Chistye Prudy neighborhood is famous for the beautiful Chistoprudny Boulevard and the pond after which the area is called—Chisty Prud (Clean Pond). In medieval times, several ponds stood on the location of the current single pond. They were used as refuse dumps and were fittingly called Griyaznye Prudy (Dirty Ponds). Under Peter the Great's reign, his friend and advisor Menshikov dredged the ponds, unified them into one pond and renamed them Chistye Prudy (Clean Ponds). There is the only tram line in Moscow Center near there.
