Doggerwerk in Happurg, Tunnel system and memorial in Happurg, Germany
Doggerwerk is a tunnel system driven into the Houbirg rock near Happurg, with eight connected galleries forming factory halls five metres high and up to seven metres wide. Its entrance is a wide round concrete arch set into a vertical rock face, closed by a barred metal door; cracks and stains mark the concrete above the arch.
From May 1944 to April 1945, prisoners of the Hersbruck subcamp of Flossenbürg built the Doggerstollen under SS direction, with planning by a Jägerstab formed on 1 March 1944. BMW was ordered to move production of BMW 801 aircraft engines from its Allach plant into the Houbirg. The code name was initially "Esche 1", changed to "Dogger" in 1945. Work stopped before production began.
The tunnels serve as a place of remembrance for the workers who labored here under difficult conditions every day. The site honors their experience and sacrifice during that period.
The entrance is sealed with a secured metal door, and the interior is not open to visitors. You can view the site from the outside and examine the historical features of the entrance structure.
Only about one-fifth of the planned 120,000 square meter underground complex was actually excavated before work stopped. Remarkably, this incomplete project never began actual production operations.
