Underground Factory Doggerwerk

In 1944, the German industry was subjected to massive Allied bombings. The German Air Force (Luftwaffe) was out powered and the only solution was therefore to bomb-proof the factories.

Therefore in May 1944 the Germans started in the Houbirg mountain east of Nuremberg, construction of an underground factory to produce the airplane engine: Hochleistungmotor BMW 801, which was used for example in Focke-Wulf Fw 190 and Junkers Ju 88.

The construction work was given the code name Esche 1 or simply Doggerwerk.

A subcamp (KZ Hersbruck) was made to the Flossenbürg concentration camp and 9500 forced workers, primarily Hungarian Jews, work in two teams to hatch and blow their way into the rocks.

Tunnels were made 5 x 5 meters and during the barely one year on which the work was done, 20% of the factory was completed and half of the workers died in the same period of illness, hunger and fatigue.

All entrants were closed after the war and today a memorial has been made on the spot. Doggerwerke never came into use and today only bats are using the old tunnels.
