The Nazi escape routes known as "ratlines" during the fall of the Third Reich led to some remote, unexpected places. One of them, according to a new report in Argentina's Clarin newspaper, led to a remote spot in a strip of jungle on the Argentina-Paraguay border.

Below, a video report from Clarin.

From the Washington Post's coverage:

According to a fresh discovery announced over the weekend, it's also true the Nazis made it deeper into the Argentine jungle in search of refuge than anyone imagined. Hundreds of miles north, along the border with Paraguay, rises the Parque Teyú Cuare. A path winds into the nature preserve, opening to a trove of "mysterious buildings" that are "battered by time," reported the Argentine newspaper Clarin. "What were these buildings? Who built them? For what?" It now appears there may be an answer. According to a team of Argentine researchers led by Daniel Schavelzon of the University of Buenos Aires, the three buildings were built by Nazis. The signs are everywhere. The team found several German coins with dates between 1938 and 1944. They found some German porcelain engraved with "Made in Germany." And perhaps most telling, they found Nazi symbols, including a swastika, were etched into the buildings.

"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," Schavelzon told Clarin. He accompanied a team of Argentine journalists to view the site and shoot amazing images of the buildings decaying in the jungle humidity.
