In Southwark, between the Cathedral and the Globe Theatre runs Clink Street. It is in that dark and dingy alley that such that remains of the notorious prison, which is now rebuilt as a museum, is found.
Narrow, dark, and cobbled, it is well-known for the chase-scene in the David Lean film Oliver Twist. http://en.wikipedia.org/wiki/Clink_Street
Now the word 'clink' is widely used in Britain for prison. 'He did a year in clink', 'At this rate he will end up in clink' etc.
What I am unsure about, is whether 'clink' derives from onomatopoeia, the sound of metal doors closing, keys, chains and fetters etc. and in that way became an everyday term for prison. Does Clink Street take its name from the prison, or did prison become known as 'clink' because a notorious one (from the 12th to 18th centuries) was located in Clink Street.
It is not clear from the quotations in the OED.
