BIGGEST UNDERGROUND BUNKER IN EUROPE // LOST AND AFRAID MAGINOT LINE

The underground series continues with the biggest underground facility we have ever visited to date. As we step into this facility it really is like stepping back 80 years to the war, This base was made to keep the Germans from entering France with over 200 miles of tunnels over the 100ft below the surface this place truly is terrifying in its dormant state. #underground #exploringwithfighters #adventure
