This bunker belongs, as a special factory shelter of the German Kriegsmarine, to a series of ten or more identically-built objects which were able to shelter 1400 people on average.
Two slightly modified bunkers of the type are situated in Kiel, the other in Schweinfurt (now already dismantled). The bunker C 178, whose designation comes probably from post-war times, has been built from the end of 1943 to the middle of 1944. It was called „ Werftbunker 1400“. (Shipyard factory shelter)
The bunker is similar to regular Kriegsmarine crew shelters, one such specimen standing near the bunker C 178 in westerly direction. The bunker was solely used as a shelter for the workers of Bremer Vulkan shipyard. Another identical bunker stood near the U-boat bunker building yard „Hornisse“.
Nowadays, bunker C 178 is being used by two different groups: At the bottom floor, TNT eventz offer club and music events. At the top floor, the Musikverein Kulturbunker Vulkan e.V. is based, which gives about 20 young bands the opportunity to play and rehearse.
