A unique site in Europe!

Discover also the incredible history of the pocket of Saint-Nazaire, the last liberated region of Europe, on 11th May 1945. A museum rich in emotions, installed in an authentic site with live reconstructions, models and a video room. A site acclaimed by more than 35,000 visitors every year!
For children from 5 to 12 years old, a new treasure hunt is on offer, for an active and fun visit. 
Reward: a real diploma will be awarded at the end of the visit.
