The 32-hectare plot in the northeast corner of the Green Island, isolated on the sea, was Vagrants Shelter during Japanese colonial rule; and it became a major prison in the White Terror period immediately after the ROC government moved to Taiwan in 1949. New Life Correction Center and Oasis Villa were set to confine political prisoners. When martial law was lifted, it was became Green Island Prison under the Ministry of Justice and then the military's moral training center for offenders.

Wax figures in the New Life Correction Center vividly retell the lives of the victims. Oasis Villa, with the eight-sided building (watching four corridors) in the center, was a concentration camp-style prison. This 50:1 model gives visitors an idea of the victims' hard labor and re-education.
