Close to Frankfurt, nearby Hofheim-Langenhain, one can find the European Bahai Temple, open since 1964 for people of all kind of religions and political views. Especially of interest, not only from photographic point of view is the extraordinary location and architecture of the building. This reveals special light effects, shadow and geometric forms, worthwhile for deeper photograhic exploration.
