Ludgate Hill was a railway station in the City of London that was opened on 1 June 1865 by the London, Chatham and Dover Railway (LC&DR) as its City terminus. It was on Ludgate Viaduct (a railway viaduct) between Queen Victoria Street and Ludgate Hill, slightly north of St. Paul's station (now called Blackfriars station) on the site of the former Fleet Prison. North of Ludgate Hill station, Ludgate Viaduct continued to the Snow Hill tunnel to connect with the then recently opened Metropolitan Railway south of Farringdon station to enable main-line trains to run between north and south London.
