A unique site in Europe!

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.

Since 2017, the museography has been renewed: more modern showcases and mannequins as close as possible to reality with a real work of personalisation.
In case of rain in summer, it is advisable to come and visit the museum during off-peak hours between 10:00 and 14:30 or between 16:30 and 19:00.
