The exhibition shows the invisible and yet the present. 75 years after the end of the Second World War. For some a time long past, for others just over and still far too close. How do a city and its society deal with the culture of remembrance? What is visible, what is not? What is done, what is omitted? What is conscious, what is unconscious? What is there without being visible? The exhibition spaces open up digitally online via the internet, 3D animations transform these virtual spaces by means of VR glasses. Thus, an exhibition appears that is not there. Can virtual reality be a reflection of our collective memory? Step into a space that is only seemingly empty and decide for yourself!
