The panopticon is a design of institutional building with an inbuilt system of control, originated by the English philosopher and social theorist Jeremy Bentham in the 18th century. The concept is to allow all prisoners of an institution to be observed by a single corrections officer, without the inmates knowing whether or not they are being watched.
This plan of Jeremy Bentham's panopticon prison was drawn by Willey Reveley in 1791.
