The Panopticon is a type of prison building designed by English
philosopher and social theorist Jeremy Bentham in 1785. The concept of
the design is to allow an observer to observe (-opticon) all (pan-)
prisoners without the prisoners being able to tell whether they are
being watched, thereby conveying what one architect has called the
"sentiment of an invisible omniscience."
Bentham himself described the Panopticon as "a new mode of obtaining
power of mind over mind, in a quantity hitherto without example."
The
panopticon was never built in the UK, but a number were built
throughout the world in more modern times, the most starkly interesting
to see is the Presidio
Modelo in Cuba...
