King William Street tube station

King William Street was the original but short-lived northern terminus of the City and South London Railway (C&SLR), the first successful deep-level underground railway in London and one of the component parts of the London Underground's Northern line. It was located in the City of London, on King William Street, just south of the present Monument station. When King William Street was in operation the next station to the south was Borough and the southern terminus of the line was Stockwell. The station was in operation for less than ten years. It was named after the street above, which in turn was named after King William IV. London Transport Museum runs regular virtual tours of the station through its "Hidden London" programme. The tour also explores how the Bank redevelopment project utilised the original 1890 station to build the current platforms and passageways.
