Bagnios were the slave prisons of Turkey an the Barbary regencies. In the Barbary prisons, the hostages of the pirates spent their evenings there, leaving during the day to work as laborers, galley slaves, or domestic servants. The term was originally used for a bath or bathing-house (Italian bagno, Spanish baño) in Istanbul, near which the prison for hostages was. Bagne became the French word for the prisons of the galley slaves in the French Navy. The last one in European France (Toulon) was closed in 1873.
