Green Island(Lyudao) was once the prison for political prisoners, whom were sent here for centralized management at the notorious Oasis Villa and Jhuangjhin Camp.

The Island was synonymous to the White Terror Period then. Now Green Island(Lyudao) is regarded as the base of human rights. The 32-hectare Green Island(Lyudao) Culture Park contains Human Rights Memorial Park, the Oasis Village, Zhuangjing Camp Area, Green Island(Lyudao) Vocational Training Institute, Swallow Cave, and coastal areas. Visitors can see the solitary cells, general cells, and isolation rooms, which remind of the victims' commitments to human rights. A list of victim names was carved on the Human Rights Monument.
