A vaguely interesting article in the Daily Telegraph today reports that Argentinian urban archaeologists have discovered buildings thought to have been built "half way through the war" for the "Top leaders" of the Reich to escape to in the event of defeat. The site is in jungle at the northern most end of the country on the border with Paraguay. I personally think having read the article and another similar in the Israeli newspaper Haaretz that the site may be more closely linked to either mining or civil engineering projects that involved German nationals as Argentina was a neutral country until March 1945. Prior to that they supplied export products to both sides (but weighted more so to the axis countries), and was also heavily influenced in it's military structure by German military traditions amongst the armies hierarchy dating back to pre WW1.
But whatever the truth may be, and whether the facts of this story even bear up to close scrutiny, remains to be seen.

And the Haaretz article that claims there were up to 18,000 German immigrants living in the area since 1940 of this "Secret Nazi Lair", which indicates to me a probable more mundane answer to the archaeologists headline grabbing claims.
Incredible discovery that may add fuel to the conspiracy theories that Hitler escaped to Argentina? Or more likely a German immigrant enclave? Only YOU can decide.....
