The "Annunciation" app shows the spiritual object (Lk. 1:37-38) of the Church of the Annunciation, which the Order had abandoned, at three locations in Berlin in the form of augmented reality. The app thus connects Berlin, the global data network and the thought of the deeply hidden deity. Commissioned by Ethos Maria e.V.. Can be seen in front of the Gabriel Monastery in Bayernallee/Preußenallee, in front of the kath. Parish of St. Marien Liebfrauen on Wrangelstrasse and in front of St. Hedwig's Cathedral on Bebelplatz.
