Stockwell is a London Underground station in Stockwell in the London Borough of Lambeth. It is located on the Northern line between Oval and Clapham North stations, and on the Victoria line between Brixton and Vauxhall stations. It is in Travelcard Zone 2. The station opened on 4 November 1890 as the southern terminus of the City and South London Railway, the first successful deep-level tube in London. The Victoria interchange opened on 23 July 1971 when that line was extended south from Victoria towards Brixton. The station is known for its World War II air-raid shelters, and for being the location of the shooting of Jean Charles de Menezes. Stockwell station was ceremonially opened on 4 November 1890 by the Prince of Wales (later King Edward VII), as the most southerly station on the City and South London Railway (C&SLR) – London's first successful deep-level tube railway. Passenger services began just over one month later on 18 December. The station was built with a single island platform with tracks on either side, an arrangement that today is rarely used underground on the network but which still exists at Clapham North and Clapham Common. Stockwell's original platform was further north than the new ones, and trains pass it today. The other terminus of the C&SLR line was King William Street in the City of London. On 3 June 1900, when an extension to Clapham Common was opened, Stockwell ceased to be a terminus. A flight of stairs at the south end of the platform was also added to take passengers to a subway that passed over the new northbound tunnel and joined the lift shaft at a higher level. The original building, designed by T. P. Figgis, was similar to – but larger than – the existing surface building at Kennington with a domed roof to the original lift shaft. The two lifts each carried 50 people to and from the platforms until their replacement by escalators in 1924. The station was modernised in advance of the 1926 extension from Clapham Common to Morden. A new surface building was constructed by Charles Holden on the original site.
