South Kensington is a London Underground station in Kensington, west London. It is served by the District, Circle and Piccadilly lines. On the District and Circle lines, the station is between Gloucester Road and Sloane Square, and on the Piccadilly Line, it is between Gloucester Road and Knightsbridge. It is in Travelcard Zone 1. The main station entrance is located at the junction of Old Brompton Road (A3218), Thurloe Place, Harrington Road, Onslow Place and Pelham Street.
Subsidiary entrances are located in Exhibition Road giving access by pedestrian tunnel to the Natural History, Science and Victoria and Albert Museums. Also close by are the Royal Albert Hall, Imperial College London, the Royal College of Music, the London branch of the Goethe-Institut and the Ismaili Centre.The station is in two parts: sub-surface platforms opened in 1868 by the Metropolitan Railway and the Metropolitan District Railway as part of the companies' extension of the Inner Circle route eastwards from Gloucester Road to Westminster and deep level platforms opened in 1906 by the Great Northern, Piccadilly and Brompton Railway.
A variety of underground and mainline services have operated over the sub-surface tracks, which have been modified several times to suit operational demands with the current arrangement being achieved in the 1960s. The Deep-level platforms have remained largely unaltered, although the installation of escalators in the 1970s to replace lifts improved interchanges between the two parts of the station. Parts of the sub-surface station and the Exhibition Road pedestrian tunnel are Grade II listed.
