Die Glocke (German for “The Bell”) was a purported top secret Nazi scientific technological device, secret weapon, or Wunderwaffe. Described by Polish journalist and author Igor Witkowski in Prawda o Wunderwaffe (2000), it was later popularized by military journalist and author Nick Cook as well as by writers such as Joseph P. Farrell and others who associate it with Nazi occultism and antigravity or free energy research.
According to Patrick Kiger writing in National Geographic magazine, Die Glocke has become a popular subject of speculation and a following similar to science fiction fandom exists around it and other alleged Nazi "miracle weapons" or Wunderwaffen. Mainstream reviewers such as former aerospace scientist David Myhra express skepticism that such a device ever actually existed.
