The museum, which was inaugurated Sunday, is exhibiting a document from A.D. 321 on the Jews who settled in Cologne.
Museum director Michael Blumenthal told ZENIT that the document is invaluable, as it shows «how Jewish citizens, who must not be forgotten, lived in Germany for a long time.»
He added: «German history cannot be properly understood without keeping their presence in mind.»
The exhibition in fact demonstrates the presence of flourishing Jewish communities in Germany from the first century.
