Nazi gold trainW
Nazi gold train

The Nazi gold train or Wałbrzych gold train is an urban legend about a train laden with gold and treasure that was hidden by the Nazis in southwest Poland during the last days of World War II. The apocryphal tale claims the train full of valuables, including artwork, was concealed in a sealed-up rail tunnel or mine in the Central Sudetes by retreating Nazis. Despite numerous searches being made since 1945, including ones by the Polish Army during the Cold War, no evidence of the train, its tracks or treasure have ever been found. Historians believe the train never existed.

Vorbunker

The Vorbunker was an underground concrete structure originally intended to be a temporary air-raid shelter for Adolf Hitler and his guards and servants. It was located behind the large reception hall that was added onto the old Reich Chancellery, in Berlin, Germany, in 1936. The bunker was officially called the "Reich Chancellery Air-Raid Shelter" until 1943, when the complex was expanded with the addition of the Führerbunker, located one level below. On 16 January 1945, Hitler moved into the Führerbunker. He was joined by his senior staff, including Martin Bormann. Later, Eva Braun and Joseph Goebbels moved into the Führerbunker while Magda Goebbels and their six children took residence in the upper Vorbunker. The Goebbels family lived in the Vorbunker until their deaths on 1 May 1945.
