Weingut I
Coordinates: 48°14′25.42″N 12°27′9.57″E / 48.2403944°N 12.4526583°E In 1944 the Third Reich began work on the construction of a partially underground bunker factory codenamed Weingut I (English: Vineyard I) in the forest known as the Mühldorfer Hart, slightly to the west of Mühldorf am Inn in Upper Bavaria. Plans for the bunker called for a massive reinforced concrete barrel vault composed of 12 arch sections under which Messerschmitt Me 262 jet engines would be manufactured in a 9-story factory. Upon completion these were to be sent to a similar installation in the area of Landsberg am Lech (codename Weingut II), where the final assembly of the aircraft was to take place. This network of underground factories was intended to ensure the production of the Me 262 at a time when the Allies had already gained control of the German airspace.
Despite it being increasingly clear to the organizers of the project that it would never be finished in time to make a difference in the war, the construction of Weingut I was approved on a 6-month time-line. Of a total of 10,000 workers who worked on the project, 8,500 were forced laborers and inmates of the Mühldorf concentration camp network. Of these more than 3,000 would die of overwork, underfeeding, and SS brutality. By the war's end, only 7 of the planned total of 12 bunker sections had been built, and construction of the factory itself had not begun.
