Nazi Megastructures: America's War - WWII Documentary Series | Historical Military Engineering | Perfect for History Buffs & WWII Enthusiasts

In the last few years I have watch a number of shows on tv that have shown MANY Nazi "mega structures." I saw this and thought it would be great to have them all covered in one DVD.I was VERY DISAPPOINTED when 4 of the 6 episodes were about JAPANESE structures from WWII. To me this is FALSE ADVERTISING!I would still LOVE to find something (a book would be even better) that describes all the mega structures the Nazis built. For example, the huge submarine facility in the Canary Islands.If you know of something, please let me know.
