Ilha Grande Prison

Ilha Grande Prison was a notorious penitentiary located on Ilha Grande island in Brazil, operational from the early 20th century until its closure in 1992. Known for its harsh conditions and high-profile inmates, it functioned as a maximum-security facility housing some of Brazil’s most dangerous criminals. The prison’s isolation and fortress-like structure contributed to its reputation as a symbol of Brazil’s turbulent penal history. Its closure led to the site being transformed into a historical and environmental reserve, attracting visitors interested in its complex history and natural beauty.
