Those crazy Nazis!

A team of Argentine archaeologists investigating a series of ruins in the jungle, close to the border with Paraguay, believe they have discovered a secret Nazi lair.

The cluster of stone structures, now covered by thick vines and accessible only when using a machete to cut through the undergrowth, contain stashes of German coins from the late 1930s, fragments of "Made in Germany" porcelain, and Nazi symbols on the walls.

"We can find no other explanation as to why anyone would build these structures, at such great effort and expense, in a site which at that time was totally inaccessible, away from the local community, with material which is not typical of the regional architecture," said Daniel Schavelzon, leader of the team.

"This site also has the bonus of allowing the inhabitants to be in Paraguay in less than 10 minutes. It's a protected, defendable site where they could live quietly."

Ultimately, though, the hideout wasn't needed, because after the fall of the Nazi regime their leaders were welcomed to Argentina and allowed to live openly.
