Nazi Megastructures (Seasons 1–6)

Nazi Megastructures (2013) is a British-American documentary series you can watch online on iFILM. Each episode takes one colossal engineering project from the Third Reich and examines how it was designed, built, and deployed — or failed — in wartime.

The show moves through Atlantic submarine pens, Hitler's mountain fortresses, the V-2 rocket facility at Peenemünde, Krupp's oversized railway guns, and more. Engineers' ambitions clashed constantly with raw material shortages and military reality, and the series traces those contradictions through blueprints and archive footage, with Richard Lintern narrating throughout. The approach is structural rather than ideological — what the Third Reich actually managed to build, at what human and material cost, and how the Allies ultimately countered each one.
