An abandoned eerie structure in France could have doomed the Allies in World War II, and new discoveries at this mysterious site reveal the truth behind top-secret Nazi plans to unleash apocalyptic destruction. Germany built the Blockhaus d'Éperlecques between 1943 and 1944 to serve as a launching pad for V2 missiles targeting London and southern England. Severe damage from heavy Allied bombing prevented its completion.
