This is one of the segregation cells at Kingston Penitentiary, or solitary confinement for friends south of the border. Inmates were assigned here as punishment for infractions, but there were also several prisoners in permanent segregation for their own safety. They were in these cells 23 hours per day, with one hour of “outdoor” time in a walled yard that was only about 15 metres x 15 metres. They had almost no interaction with any other human being.
