The lack of museums covering communist-era East Germany is startling. The few DDR* museums that exist are zero-budget independent shoestring operations such as this one that simply took over a few floors of an unrenovated office building, not even in Dresden itself but in a town just outside it. The government seems to have little interest in documenting East German history. Exceptions include the main German history museum in the little, not-centrally-located town of Bonn (West Germany’s capital until unification) and two small DDR-related museums in Berlin that only opened around 2011-13.
The sinks are not a display. The photo is here to show the curious German (European?) habit of having sinks out in the hallways of office buildings.
*DDR was East Germany, Deutsche Demokratische Republik. West Germany was BRD, Bundesrepublik Deutschland (Federal Republic of Germany)
