Loire-estuary shipbuilding port on the Atlantic
Saint-Nazaire sits at the mouth of the Loire on the Atlantic coast and is one of France's main shipbuilding centres, building large cruise liners. A vast wartime U-boat pen still stands on its waterfront.
The town grew rapidly in the 19th century as an ocean port and shipyard for Nantes upriver. Its concrete submarine base made it a heavy Allied bombing target in World War II.
