With the Signal Festival app you can follow the light throughout the whole year.

The app combines the historical scenery of Prague and modern digital technology.

It features the unique Signal AR route. Art installations hidden in augmented reality are waiting for you. Download our app, head to Karlín, discover & share art in augmented reality.

Thanks to this route we can be with you all year round. At selected locations it is possible to view the art installations via phone or tablet. For the best experience, we recommend visiting the installations during daylight hours, i.e. between 8am – 7pm depending on the time of year.

Signal AR is an augmented reality experience. We have prepared art installations for the 9th Signal Festival in 2021 in response to the global pandemic.

The Signal AR project was developed in collaboration with the creative studio Brainz Immersive, bicepsdigital and artists. As part of Signal AR, you can visit five art installations that you can view through your phone’s display. Simply download our festival app, head to a point along the Signal AR route, scan the Signal sign, and then discover the works in augmented reality through your phone. You don’t need anything else. Imagine if there was no sharp line between your own imagination and the real world. No entrance fees, no opening hours, no barriers. Experience Signal AR.
