It is mostly an unremarkable location, except for the fact that it is in a bit of a shambles. Something has obviously taken place here, but the smooth surfaces and sharp edges of the architectural detail simply do not offer up any artistic intention.
Actually, Thomas Demand's "Room" (1994) is a surprising re-creation of the conference area where Count Claus von Stauffenberg attempted to assassinate Hitler in 1944. Demand photographs crime-scene models he makes from cards and paper, but he leaves viewers without the benefit of the essential historical details. The picture is an abstracted construction -- erasing "evidence" -- that makes observers wonder if real historical settings might be so entirely sanitized of historical associations.
Demand's work is a good example of the multiple threads that run through contemporary German photography, which can be summed up as the documentation, interrogation and erasure of recent memories.
