Deep in the remote jungle of northern Argentina are three long-forgotten stone structures, but who allegedly built them might surprise you.
The researchers from the University of Buenos Aires base their hypothesis on several German coins, a shard of a porcelain plate and at least one swastika carved into the stone.
The coins were minted between 1938 and 1944, during the Nazi Third Reich. An inscription on the plate fragment reads "Made in Germany." (Video via Clarín)
As the leader of the research team tells Argentine newspaper Clarín, "Apparently, halfway through World War II, the Nazis had a secret project of building shelters for top leaders in the event of defeat — inaccessible sites, in the middle of deserts, in the mountains, on a cliff or in the middle of the jungle like this."
In Argentina, Nazis didn't need secret hideouts to escape authorities. (Video via YouTube / travelfilmarchive)
Then-Argentine-President Juan Peron allowed scores of former Nazis into the country through escape routes called "ratlines" after the war. (Video via YouTube / TV Pública - Argentina)
Among them, Adolf Eichmann, one of the main orchestrators of the Nazi Final Solution, was captured in Argentina in 1960. He was later taken to Israel, where he was tried and executed. (Video via British Pathé)
According to The Washington Post, one of the three buildings was likely used for housing, one for storage and one as a lookout.
The structures lie in Argentina's Teyú Cuaré park in northern Argentina near Paraguay.
