Going underground
In the Pays Thionvillois, even in scorching heat, it’s still possible to combine discovery and coolness. Go a few kilometers underground, where you’ll find the memory of the epic of the iron mines and the Maginot Line. Immerse yourself in the day-to-day life of the gueules jaunes and the French soldiers of the Maginot Line. Discover their tricks, their modernity and their know-how in these galleries and concrete bunkers, which emerge from the ground like burrows.
These sites are guaranteed to maintain a constant temperature of 12 degrees all year round. But beware of temperature variations! Don’t forget to bring a sweater or cardigan for your visit, even if it’s hot outside.
