Bank and Monument are interlinked stations, officially a station known operationally as the Bank-Monument complex. However, the separate names are used on station entrances, all platforms and the tube map. The station spans the length of King William Street in the City of London, turns along the loop of Mansion House and Cannon Street stations. Together, they form the eighth busiest station on the London Underground network, being served by five London Underground lines and the Docklands Light Railway (DLR).
