History & geography

History

For almost a century, the Brazilian government declared the island off-limits, banning unauthorized entry, as it had contained an immigration quarantine station and, later, a maximum-security prison (Colônia Penal de Dois Rios, later known as Instituto Penal Cândido Mendes). The Cândido Mendes Penal Colony, which housed some of the most dangerous offenders in Brazil, was closed in 1994. On 1 January 2010, devastating mudslides killed at least 19 people on the island. On 5 July 2019, Ilha Grande and Paraty were inscribed as a UNESCO World Heritage Site.
