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 & South London Railway (C&SLR) - London's first deep level tube railway. Passenger services began just over one month later on 18 December 1890. The station was built with a single island platform with tracks on either side, an arrangement rarely used on the Underground network, but which exists today at Clapham North and Clapham Common. Stockwell's original platform was further north than the modern ones, and trains pass them today. The other terminal of the C&SLR line was King William Street in the City of London. In 1900, Stockwell ceased to be a terminus, after the opening of an extension to Clapham Common. 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 the mid-1920s.
With the opening of the Victoria line on 23 July 1971, parallel cross-platform interchanges were provided between the two lines in both directions and the 1920s surface buildings were replaced by a modern structure. A British Transport Police station was later built above the station. On 22 July 2005, Jean Charles de Menezes, a Brazilian electrician living in London, was shot dead by plainclothes police officers at Stockwell station. This incident came a day after the failed 21 July 2005 London bombings occurred on Tube trains and a bus in London; however, it later emerged that it was a case of mistaken identity on the part of the police and that Menezes had nothing to do with the attacks. The station has ticket halls, three escalators, 7 gates, 13 payphones, a Wifi service, 9 vending machines and a photo booth. The ticket hall has electronic departure boards.The ticket office was closed in early 2015 as part of the TfL investment programme.
