What a contrast to the synagogue of 1827, which was still hidden in a backyard: In 1870, the New Synagogue by the eminent Jewish architect Edwin Oppler was inaugurated on an open square in Hanover's Neustadt. In its size and the chosen architectural style, the new building expressed a growing self-confidence and the belief that as Jews they had arrived in German society on an equal footing. For, Oppler said, "The Romanesque style is German through and through."
