Not really. This is a mangled re-report of a truly stupid BILD 'story' (even by their low, low standard). The only thing 'found' was some cellars were some cognac and champagne was stored toward the end of WW II. It's even mentioned that everything stored there was looted by Russian troops. NOTHING THERE TODAY. Guess that was too hard to comprehend for the re-reporter.
The original BILD non-story is little else than cheap publicity for the new owner of the place.
But this goes to show, again, how the gullible can be duped into believing almost anything.
True dat!
