📝 About this app
"Stolpersteine commemorate the victims of the Nazi regime. With texts, photos, audio, graphic stories and augmented reality elements, the app provides interactive information about people who lived in your street or town during the Nazi era: Stolpersteine NRW brings history to life.
Note on use: This app uses Google Maps to navigate to the Stolpersteine and the Google Firebase service, which is required for the AR functions. This transfers data to Google.
There are around 17,000 Stolpersteine in North Rhine-Westphalia, which have been laid in more than 280 cities. Each stone commemorates a person who was a victim of National Socialism.
Stolpersteine NRW takes you on an interactive journey to where the victims last lived before they were forced to flee, commit suicide or were deported.
Stolpersteine NRW provides information about the individual lifes of the victims, for example in the form of:
- biographical texts and audio stories
- artistic illustrations in the form of graphic stories
- historical photos, audio recordings and videos
- augmented reality content
Additionally, there are the following contents:
- Map with all Stolperstein locations
- Suggestions for Stolperstein routes through North Rhine-Westphalian cities
- Teaching material (in cooperation with “Planet Schule”)
- Interactive filters for searching and researching all 17,000 data records
Experts from more than 250 cities in North Rhine-Westphalia have supported this project. Without their knowledge and research support, the project would not have been possible.
We look forward to receiving feedback at stolpersteine@wdr.de!
