It was built in 1877/78, designed by architect Hermann Behaghel. The prayer room that had been used since 1714 in the older house “The Blue Lily” had grown too small. The city of Heidelberg redid the square with support from a citizen’s initiative, with white marble paving stones marking where the walls of the destroyed synagogue once stood. Gray granite indicates the windows and entrance. Twelve sandstone cubes, some of them illuminated, symbolize the pews and recall the twelve tribes of Israel.
