They believe it was proactively built to house top Nazi members in the case of their defeat in WWII.

Researchers from the University of Buenos Aires (UBA), together with archaeologists from the Museum Andrés Guacurarí, stumbled upon ruins of a site that is believed to have been erected to house high-ranking former Nazi officials.

The team is studying the buildings laying in relatively inaccessible part of the Teyú Cuaré Park, southeast of Misiones, on the border with Paraguay.

The cluster consists of three stone structures, now covered by thick vines: Living quarters, a warehouse and a third structure that apparently served as a half-hidden lookout. The place is believed to be strategically sought by whomever built it, as it has a panoramic view and walls that are three feet thick. It also has an easy escape route to neighboring Paraguay, in the case that someone might have to quickly flee the country.
