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 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 terminal at Tower Hill.
