The Star of David was and is an Indian symbol (from BCE), A Christian symbol (from first century CE), a Muslim symbol (From 7th century CE) and a Jewish symbol from the middle ages. It is shared by all the major religions and thus it fits to serve as a future shared inter religious emblem.

Pay attention to the small yellow Star of David on the left of the chandelier. It is part of a series of attempts to let the three monotheistic religions find expression in one magnificent building.
