Île Longue (French pronunciation: [il lɔ̃ɡ]; French for "Long Island"; Breton: Enez-Hir) is a peninsula of the roadstead of Brest in the department of Finistère in the Brittany region. It is the base of the French nuclear ballistic missile submarines (French: sous-marin nucléaire lanceur d'engins, SNLE), and as such one of the most secretive and heavily defended places in France.
