1 – Project Riese
Riese in German means “Giant” and is the code name for a secret construction project, where the Nazi’s built seven massive underground bases between 1943-1945 in the Owl Mountains and Książ Castle in Lower Silesia, Poland.
With increased aerial raids by the RAF across Nazi Germany and allied air superiority in the later years of the war, high command took the strategic decision to move large parts of its armaments and production infrastructure underground.
It’s assumed that Project Riese is one such armaments factory, but a lack of documentary evidence surviving the second world war has left historians debating over the true function of Riese.
