Ventilation shaft close to the main entrance (destroyed by Allies after WWII) on the level of 7th floor of Stohr 1 Hammerwerke underground factory inside Jakobsberg in Porta Westfalica, North Rhine Westphalia, Germany. May 11th 2015. Since 1943 Nazi Germans started a major programme, called U-Verlagerung, of relocation key war industries from surface to underground locations to avoid Alliance bombardment. Inside sandstone Jakobsberg two underground factories were built using the old quarries. In lower part one-level code name Dachs 1 was built from March to August 1944 for Ambi-Budd company, manufacturer of airplane frames. Changed in August 1944 for Deurag Nerag company from Hannover, more important as a part of so-called Geilenberg program (as 1 of 9 installations) in production of lubricating oil (Schmieröl) synthetic fuel. Relocation was planned to finish in May 1945 but in the end of war construction was 85% complete. In upper part of Jakobsberg there was 9 underground level code name Stohr 1 called Hammerwerke built from March to September 1944 for Phillips Radio Valve (Philips - Valvo - Röhrenwerke) factory from Eindhoven, Netherlands, to produce radio tubes and radio measuring from February to March 1945. Rentrop company from Stadthagen also used a small part of Stohr 1 to produce remote controlled bombs. After the war, entrances to both structures were destroyed by Allies. Now, Dachs 1 is closed for visitors, but is planned to open in future. Stohr 1 is in very poor condtion and closed from safety reasons as a very dangerous to explore © Wojciech Strozyk / Alamy Stock Photo
