Yes, something sort of like that did happen! I have written a post regarding Ahnenerbe's (theoretical) search for Atlantis, where I also briefly talk about Heinrich Himmler's search for the Mjölnir, the mythical hammer of Thor, the Norse god of thunder.

Keep in mind that this is "Askhistorians", not a sub dedicated to discussing contemporary cinema or comic books. Please do not post things like "you forgot about X-film-with-Nazi-occult-stuff!" or about the intricacies of Marvel comic book plotlines. Thank you.

My dad goes on and on about Hitler and the search for the Spear of Destiny. I listen, politely, but I just don't buy it. Any truth to any of it?

Follow-up question: How did it become well-known that the Nazis were into this stuff? When Raiders of the Lost Ark came out, was it already common knowledge?

I can't remember where but I heard that the Germans sent a search party into the Himalayas to search for 'Shangri La', can anyone clarify?

I've read that when they took Czechoslovakia, the Nazis tried to find the legendary "Golem of Prague" (the mythical Jewish Frankenstein that story tells is hidden in the Altneuschul). Any truth to this?
