Now showing on the Science Channel, "Secret Nazi Ruins" 10 Oct,2019 episode... all about Dag Bromberg and the DAG ammunition plant of WW2 outside of one of Poland's largest city's. The largest ammunition plant of the war, built under the canopy of the forest containing 1,000 + buildings with the latest technology of the time, And yet it was never discovered and remained in operation throughout the war (until the Russians pushed the Germans out of Poland).
A must see, still watching, but did a search and apparently it has been made into a museum.
LinkThe last statement of the show was that while the Germans tried to destroy as much as possible in the last days of the war shortly before being overrun by the Russians, As the U.S also did, the Russians used thousands of trucks removing material and secrets from the plant after its capture. And might have captured plans for the German V-4 rocket.
