Apparently an amateur archeologist discovered this underground bunker complex near the facility that developed the me262 jet, all based on CIA records. Also, there is apparently evidence of radioactivity in the tunnels so he thinks the Nazi's did nuclear weapons research here. Are there any more credible sources on this than a TV show and the Independent? What all do we know about this facility Here's a link to the place in question, not an amazing source so I'm skeptical. https://www.independent.co.uk/news/world/europe/secret-nazi-nuclear-bunker-discovered-in-austria-9948647.html
These claims are not credible. I've written at length about them here. No historical substance to them, all hype, all trying to generate money for a documentary project. Bad history meets bad journalism. There's a reason you can't find follow-up stories and there's a reason the only news sources that covered the story in the first place are pretty unreliable.
