Batterie Todt was the prestige project of the Todt organisation, Hitlers own construction unit. Building the Atlantik Wall, Todt wanted to show what they could do so they constructed "Batterie Todt", a series of 4 immense bunkers with 1 sole purpose .. shooting gigantic bombs at the UK. Allied forces bombed the hell out of the Batterie and 1 bunker completely collapsed. Historians believe that there is treasure hidden beneath the collapsed bunker but its just to dangerous to go and look for it ... until now !
