Nazis in Antarctica

Neuschwabenland is an area in Antarctica that was discovered and mapped during the German Antarctic expedition (1938- 1939). Conspiracy theorists believe that the Nazis established a secret base here, which is still active and inhabited by survivors of World War II. Allegedly, they had discovered the entrances to the ‚Hollow Earth‘ and would have a hot line to extraterrestrial civilizations. With their help, they would develop flying saucers and advanced weapons systems to prepare for the resurrection of the Third Reich and the reconquest of the world.
However, there is no evidence for any of these Nazi-nostalgic fantasies and speculations.
