Whether gothic, baroque, or modern: Germany has a wealth of houses of worship that are worth seeing. And many of them house unknown art-historical gems. With their free app, the Protestant Church intends to heighten appreciation of such treasures. Via a radial search on a smartphone, tourists and locals can find nearby churches easily. A digital data sheet provides information on opening hours and masses as well as links to the respective parishes. Spoken texts and videos on different churches, a children's audio guide, and a theological architectural glossary make the offer wide-ranging and user-friendly.
