Wenceslas Mine

 was a mine in the Sudeten Mountains in Poland.

In 1944, the Nazis turned it into a test site known as "the Henge" or "the Fly Trap" where SS General Hans Kammler oversaw "Project Chronos". The project was powered by hydroelectricity from a nearby dam and labour was performed by inmates from a concentration camp located in the same area.

The project was unsuccessful, with many scientists being killed testing Die Glocke. The camp inmates were murdered through use of the machine to keep the experiment a secret. Kammler and Die Glocke were removed from the site in a U-boat, which took them to the secret Nazi base in Neuschwabenland in Antarctica. (PROSE: The Crawling Terror)
