Definition of devils island in English English dictionary
French Île du Diable Rocky islet off the Atlantic coast of French Guiana. The smallest of the three Îles du Salut, it is a narrow strip of land 3,900 ft (1,200 m) long and 1,320 ft (400 m) wide. Part of a penal settlement since 1852, it housed the convicts' leper colony until the islands were made a maximum-security area. It shared the notoriety for cruelty of the mainland French Guiana penal colony. Spies and political prisoners, including Alfred Dreyfus, were held there. The island's use as a penal colony was phased out by the early 1950s
