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 incarcerated being able to tell whether they are being watched, thereby conveying what one architect has called the "sentiment of an invisible omniscience."
