Tower Hill is a London Underground station at Tower Hill in the London Borough of Tower Hamlets.
The station is in Travelcard Zone 1 and near the Tower of London. The entrance to the station is located a few metres from one of the largest remaining segments of the Roman wall which formerly surrounded what is now the City of London.
It is on the Circle Line between Monument and Aldgate, and the District Line between Monument and Aldgate East. It is a few metres to Tower Gateway DLR station and Fenchurch Street railway station. The station is currently undergoing much delayed refurbishment with completion now due sometime in 2008.
It was built on the site of the former Tower of London tube station that was closed early in the history of the Underground. It replaced a station with the same name, but earlier called Mark Lane tube station, that was situated further west.
This station has three platforms, with one platform for trains that terminate at Tower Hill.
