Which island off the coast of French Guiana was site a notorious prison?

Devil's Island (French: Île du Diable) is a small island located about 11 kilometres (6.8 miles) off the coast of French Guiana, South America. It is about 14 kilometres (8.7 miles) long and about 4 kilometres (2.5 miles) wide and has an area of about 21 square kilometres (8.1 sq mi).

Devil's Island is best known as the location of a notorious French penal colony, which was in operation from 1852 to 1953. The penal colony was notorious for its harsh conditions, including hard labor, tropical diseases, and poor sanitation, which resulted in a high death rate among the prisoners.

The French began using the island as a penal colony in the mid-19th century, and it quickly became one of the most feared prisons in the world. Devil's Island was reserved for the most dangerous and incorrigible criminals, including murderers, rapists, and political prisoners.

The living conditions on Devil's Island were extremely harsh, and the mortality rate among prisoners was very high. Many of the prisoners died from disease, malnutrition, or injuries sustained during their labor. The prison also had a reputation for brutality, and prisoners were subjected to beatings and other forms of mistreatment.

The French penal colony on Devil's Island lasted for over a century, and it was not until 1953 that the prison was finally closed. In 1965, the island was opened to tourists, and it is now a popular tourist destination.
