In 2008, a violent storm struck the Danish coast causing massive waves that crashed onto the beaches revealing a secret that's been encased in the sand for nearly 50 years — World War II-era Nazi bunkers.
Reportedly, the occupying Nazis buried the bunkers under about 30 feet of sand before abandoning the area as they returned to Germany at the end of the war.
These bunkers were three of 7,000 that the Germans built as part of Hilter's "Atlantic Wall," a series of defensive fortifications that stretched from Norway, down the French coastline and to the Spanish border.
The bunker's walls are constructed with six feet of solid concrete, and most of the artifacts found inside appeared as if the Nazis quickly departed. The entombed objects consist of Nazi pennants, assorted weaponry, and radar equipment.
These secretive bunkers housed large rooms that could support code breaking and the control center for the German "Night Fighters" — an elite squadron of Hitler's Luftwaffe.
These German pilots would execute high-priority missions in the pitch black night sky which terrorized Allied forces.
"If I was Hitler and if I was trying to get out, I would want to come to Denmark, " one historian explains. "It's the one place where the Germans are still occupying, you've got the secured bunkers, you've got the radar systems, and you've got troops."
