Under lock and key

See what life was really like behind bars, as costumed interpreters take you on a tour of the Tower Of London's upper and lower Salt Towers - starting at the five-star accommodation and ending with the smaller and danker cells, inhabited by poor and friendless prisoners.

Costumed interpreters play the jail staff and arresting officers and stage mini-trials for the benefit of prison 'guests'. Tours take place six times a day. Afterwards, you can visit the new Prisoners Of The Tower exhibition, looking at documents and personal possessions relating to famous inmates.
