Weingut I

In 1944 the Third Reich began work on the construction of a partially underground bunker factory codenamed Weingut 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, where the final assembly of the aircraft was to take place.
