Doggerstollen

The tunnel was built in May 1944 to April 1945 by prisoners of the concentration camp Hersbruck, a subcamp of the Flossenbürg concentration camp, in forced labor. Here should be produced for a planned underground factory (U-relocation) war-important BMW aircraft engines. The construction management and the SS command staff were in Happurg. The cover name was "Ash 1".

The tunnels are now walled and enter only with special permission through normally closed doors. Efforts are currently underway by the association "Dokumentationsstätte KZ Hersbruck" to open a tunnel section of around 250 meters as a historical document and to make it accessible.

The Doggerstollen (also called Doggerwerk) is a tunnel system in the Houbirg mountain range. The tunnels of the Doggerwerk were forced laborers from 1944 to 1945 from the Hersbruck satellite camp. War-essential BMW aircraft engines were to be manufactured in the planned underground production facility. The site management and SS management staff were located in Happurg. The completed total length is 3.9 km, today there are still 2.6 km of it. The camouflage name was "Esche 1". It has been planned to make parts of the public accessible for some time.

Very interesting facility with a nice information board.

Very interesting history would be a challenge to make this tunnel system accessible to the public again.

Doggersberg - concentration camp forced labor camp: The tunnel was built from May 1944 to April 1945 by prisoners of the concentration camp Hersbruck, a subcamp of the Flossenbürg concentration camp, in forced labor. Here should be produced for a planned underground factory (U-relocation) war-important BMW aircraft engines. The construction management and the SS command staff were in Happurg. The cover name was "Ash 1".As a rule, the prisoners came on foot the five-kilometer-long route from the barracks camp in Hersbruck and worked in two shifts. From Pommelsbrunn station, a conveyor track led up to the Houbirg construction site for material transport. By the end of the war, 0.5 million cubic meters of sandstone were broken in 3.9 kilometers of tunnels; of which about 750 meters were concreted. The total area should have been 100,000 square meters, of which only 15,000 square meters were completed. During this time, the concentration camp outside camp was occupied by around 9,500 prisoners, during which time around 4,000 people lost their lives due to working and living conditions.Source: Wikipedia (de.wikipedia.org/wiki/Doggerstollen)
