Through QR codes on site and in public space you can soon learn more about the city’s history of society, art and culture. The information available is much more extensive than is possible with only traditional memorial plaques. By scanning the respective code, the user is led to a webpage of the Department of Remembrance Culture and History (of the Office for Further Education and Culture) and is provided with further information. The pilot project was located at Rosa-Luxemburg-Platz and two additional QR codes were installed at Koppenplatz in 2020.
