Mind control prison. It was built from 1926 to 1931 and held 6,000 prisoners, Wikipedia says.
Fidel Castro was jailed on the Isla de Juventud after his failed attack on the Moncada barracks in 1953. He stayed at the Presidio prison, designed so that prisoners can't see if they are being watched. An English philosopher and social theorist named Jeremy Bentham created this design in 1785. He called it a new way to get "power of mind over mind."
Bentham wrote that his design was useful no matter the purpose of the building
whether it be that of punishing the incorrigible, guarding the insane, reforming the vicious, confining the suspected, employing the idle, maintaining the helpless, curing the sick, instructing the willing...Guards can't observe inmates "during every instant of time," Bentham wrote, but prisoners should believe they are being watched at all times.
