Nazi party rally grounds: An expansive field, known as Zeppelinfield, which played host to military rallies.

Far off in the distance, you can barely make out a swastika in the middle of an all-white ledge. That's where Adolf Hitler delivered his rousing speeches to the Nazis assembled before him, the field filled to capacity.

The rally grounds were supposed to include 4 square miles of structures, though most of the components never came to fruition.

That includes a Congress Hall, several deployment fields, a "great road" for Nazi parades, and a stadium that never rose from its foundation.

 Lichtdom: Over 150 light beams arranged in a square around the Nazi party rallies at Nuremberg, which Speer called the "cathedral of light."

 Despite heated resistance from Hermann Göring, one of Hitler's top Nazi leaders, Hitler borrowed the searchlights from the German air force.

The move convinced the world, Hitler surmised, that the Nazis had unlimited searchlights at their disposal, despite them actually being in short supply.

Of the effect created by the beams of light, Speer said, "The feeling was of a vast room, with the beams serving as mighty pillars of infinitely light outer walls."
