Saint-Nazaire submarine base

Ville Port

This colossal WWII concrete fortress, built in just 16 months by the German navy, has been brilliantly reclaimed as Saint-Nazaire's cultural heartbeat. Wander through 14 massive submarine pens, then ascend to the 9-meter-thick rooftop for sweeping views over the Loire estuary, shipyards, and bridge.
