Interactive journey through time with the MauAR App and AR Stories on Facebook Messenger

In addition to many classic offers, you could also take on completely new perspectives through innovative formats of the festival week: The augmented reality app MauAR tells the story of the Berlin Wall as well as important episodes of the Peaceful Revolution. In addition, there were 30 places throughout the city where you had the opportunity to look at virtual stories on Facebook Messenger.

You could use your own smartphone or tablet to access the MauAR app and the augmented reality stories or borrow equipment free of charge at any of the info points at the festival pavilions.


The Wall in 3D: MauAR

Where did the Wall stand? The fact that we can ask this question in Berlin today is an achievement in itself. Thirty years on from the Peaceful Revolution, the traces of the Wall have vanished in most parts of the city. Modern technology can help us to better understand the dimensions of the Berlin Wall. The MauAR app brings the Wall to life on smartphones as an augmented reality experience. Just open the app and a movable 3D model of the Wall will appear on the screen. Users can jump between three points in time – 1961, 1971, 1981 – to follow the development of the Wall from an improvised barbed wire fence to a massive concrete wall along a death strip. In a world first, users can experience Berlin’s most famous invisible landmark along its full length of 160 kilometres around West Berlin.

In a series of interactive episodes, two fictional characters – Andreas from East Berlin and Johanna from West Berlin – share their personal stories of the Wall and take users on a journey through time.

Five special episodes throughout the festival week

Five special episodes were available throughout the festival week. On Alexanderplatz, for example, you could join the demonstration of 4 November 1989. Elsewhere, at the former headquarters of the Stasi, now the site of the Campus for Democracy, an episode explored the topic of state surveillance and spying. There are other episodes at the Gethsemane Church, at the Brandenburg Gate and at Kurfürstendamm.

The MauAR app was developed by Peter Kolski/Beta Room; the special episodes were created in cooperation with Kulturprojekte Berlin. Further information at

PLEASE NOTE: Due to the ongoing preparations for the Stage Show at the Brandenburg Gate on 9 November, the MauAR episode could not be used that day.

AR Stories on Facebook Messenger

History also came to life in over 30 augmented reality stories that could be unlocked at historical locations on Facebook Messenger via QR codes. You could take to the streets with the skateboarders at the East Side Gallery, learn about the women who fought for freedom on Alexanderplatz, and join the “Wall-peckers” at the Brandenburg Gate. The stories even brought to life Birgit Kinder’s world-famous mural depicting a Trabant car breaking through the Berlin Wall at the East Side Gallery.

The augmented reality stories were developed and produced by Kulturprojekte Berlin, Facebook and ZDF Digital. They were only available during the Festival Week.
