A couple of urban explorers discovered a gigantic secret World War I & II military bunker hidden away in a forest in France. As of now they are keeping the exact location a secret. All that is known is that it is excavated out of solid rock and located deep underground.
The bunker—which is located somewhere in France—was used during World War I and II. It contains all kinds of vintage weapons, from a German 77mm Model-1896 WW1 cannons to tanks, armored vehicles and military trucks that are almost intact.
