Three strange buildings hidden away in an Argentine jungle may have been a secret lair meant to house Nazis who fled from Germany after World War II. According to the BBC, researchers from the University of Buenos Aires investigated the buildings after hearing local rumors that they had housed one of Hitler's aides. While they reportedly don't believe that specific rumor to be true, they say that they did find German coins and porcelain at the location. The coins were dated in the 1930s and '40s. The buildings are located in the northeast corner of Argentina, in a nature reserve near the border of Paraguay.

The researchers reportedly told Clarín that the buildings' architecture was notably different from anything in the area around them. But despite their oddities and apparent links to Nazis, the researchers say that the buildings' exact purpose and the circumstances of their creation are still unknown. It's likely that Nazis never actually lived there, because Argentina, ultimately, proved friendly to Nazis and allowed them to stay in the country quite freely.
