The place where most of the political prisoners (such as Shih Ming-teh) were held was "Green Island Lodge" ("Lǜ Dǎo Shānzhuāng"). "Oasis Village" was the main penal colony. The prison was later closed, and its interior is now open to the public. "Green Island Prison" ("Lǜdǎo Jiānyù") is also on the island and has housed prisoners considered to be among Taiwan's most dangerous criminals and gangsters. However, this has changed in recent years.
