There are many old facilities on the island, including the prison facilities, but also small cities built for and by the inhabitants of the quarantine camp, and for the staff that serviced the camp and the prison.
Hai moitas instalacións antigas na illa, incluídas as instalacións penitenciarias, pero tamén as pequenas cidades construídas por e para os habitantes do campo de corentena e para o persoal que atendía o campamento e a prisión.
