The retired mechanical engineer and hobby historian made the alleged discovery in Eastern Germany under the Jonastal – a valley situated in the country’s Ilm-Kreis district.

Using a combination of ground-penetrating radar and 3D imaging technology, Lohr has identified what he believes to be five nuclear bombs hidden underground by the Nazis at the end of WWII.

“The metal’s been lying there for 71 years,” he said during an interview. “At some point it will decay and then we will have a second Chernobyl on our hands.”

Not everyone however is convinced that his discovery holds merit, especially given that there is no conclusive evidence to suggest that the Nazis ever managed to develop working nukes.

Lohr even approached local authorities about it but received a less-than-enthusiastic reply.

“They just told me that I’m not allowed to continue my research anymore,” he said.
