Nowa Huta - a model socialist town, or rather the utopian dream of one. This neighbourhood outside of Kraków was a flagship socialist realism building development from the times when comrade Stalin kept watch from the Kremlin. The threat of nuclear war during the Cold War era suggested that all the buildings should be designed with air raid shelters. Do they really exist, or are they just another Polish myth? Many stories have been told about these mysterious corridors leading to who knows where, and of people disappearing in them. How much truth there is to these tales one can find out during this underground exhibit at the Nowa Huta Museum. Dare to take a stroll down the mythical underground corridors? Perhaps you will discover a part of Polish history not visible from the surface.
