Kennington is a London Underground station on Kennington Park Road in Kennington within the London Borough of Southwark. The station is at the junction of the Charing Cross and Bank branches of the Northern line to the north and the Morden and Battersea Power Station branches to the south. Its neighbouring stations to the north are Waterloo on the Charing Cross branch and Elephant & Castle on the Bank branch; the next stations to the south are Oval and Nine Elms. The station is in both Travelcard Zones 1 and 2. The station was opened in 1890 as part of the world's first underground electric railway and its surface building remains largely unaltered. In the 1920s, the underground parts of the station were reconstructed so that the line could be extended and larger trains could be used. Two additional platforms and later several cross passages were provided for interchanges between the branches.
