The worst offenders at Port Arthur were subjected to the worst punishment: total solitary confinement. After the Separate Prison was built in 1849 – originally called the Model Prison – inmates were issued a number and then locked in a cell. Absolute silence was maintained at all times. They were only allowed isolated exercise for one hour a day and restrained in a cubicle at chapel when they attended services four times a week. While being transported, they wore a hood. If they caused trouble, it only got worse. They were subjected to a cramped, completely dark cell for up to 30 days.
