Yitzhak Navon, scion of Spanish Jewish exiles, explores Jewish landmarks in Spain. He discovers that the inhabitants of La Guardia still believe in “blood libel.” In the Jewish quarter of Saragossa, he discovers the house where his ancestor Jacob Naon (Navon) lived 600 years ago. “I travel through this vast country and often get this strange sense that 500 years after the sudden and complete destruction of the Jewish existence, their spirit still hovers over all these places. The power of memory is immense,” says Navon.
